Are CO2, temperature, humidity and CO recorded simultaneously?
Yes. If desired, it is possible to disable recording of one, two or three of the parameters to conserve memory.
Are there special considerations if I want to make outdoor measurements?
The Q-Trak™ Plus IAQ Monitor may be used to make CO2 measurements in ambient temperatures down to 41°F. When moving the instrument from a normal indoor temperature to a cold outdoor temperature, measurements will be correct for about fifteen minutes before the temperature change will begin to impair accuracy. The same fifteen minute period would apply when moving the Q-Trak Plus monitor from a cool temperature to a warmer temperature.Humidity sensor readings taken in direct sunlight exposure may not be as accurate. Shade the probe to avoid false humidity readings.
Can I calibrate the CO sensor in the Q-Trak™ Plus IAQ Monitor?
Yes. TSI calibration kit number 8939. Each calibration uses a minimum of 1 minute of each gas (zero gas and span gas). Each of the two cylinders contains approximately 340 minutes of gas. Allowing for gas loss due to normal handling procedures, the TSI calibration kit will provide 100-200 calibrations of the CO sensor in the Q-Trak Plus.
Can I calibrate the CO2 sensor in the Q-Trak™ Plus IAQ Monitor?
Yes. Calibration is straightforward and can be performed using a calibration kit available from TSI. Calibration can also be performed with your own equipment and supply of laboratory quality pure nitrogen gas (or zero air containing no CO2) and CO2 gas (500-5000 ppm). A calibration collar is provided with the Q-Trak™ Plus IAQ Monitor to accommodate calibration. Flow rate for calibration should be at least 0.3 L/min but not greater than 3 L/min.
Can I calibrate the temperature and humidity sensors?
Yes. The procedure is detailed in the Operation and Service Manual. Calibration would require an independent temperature or humidity measuring device with specifications at least as good as the Q-Trak™ Plus IAQ Monitor. Calibration service is also available from TSI with a typical turn-around time of two business days. Yearly factory calibration is recommended.
Can logged data be transferred to another database or spreadsheet for reporting or data analysis?
Yes. Data can be exported in standard comma-delimited ASCII format. Most spreadsheet and database programs can read this format. (TrakPro™ Data Analysis Software version 1.1 or higher required.)
Can the CO sensor be replaced in the field?
Can we copy the software for use on other computers?
Yes. The software is copyrighted, but may be copied to enable use of TSI products with several computers.
Does the CO sensor respond to gases other than carbon monoxide?
Other than carbon monoxide, the Q-Trak™ Plus IAQ Monitor CO sensor does not respond to chemicals commonly found in air. This is accomplished by an internal filter designed to remove interfering gases commonly found in air. The filter provides more than two years of interference protection from normal ambient levels of various common constituents as follows: To assure maximum filter life, avoid using the Q-Trak Plus monitor in areas with higher than normal concentrations of these compounds for periods longer than necessary. Storage of the Q-Trak Plus monitor in areas of high concentrations will also cause degradation of the filter even if instrument is turned off.At very high gas concentrations at the threshold limit value, the Q-Trak Plus monitor CO sensor responds to other gases as follows: *TLV not available. Number represents example concentration.
How can I adjust the sampling time when taking air velocity measurements?
In the Q-Trak™ Plus IAQ Monitor, each sensed parameter is measured internally at least once per second and is referred to as an instantaneous value. A single instantaneous value is not the best representation of an accurate IAQ parameter measurement. Rather, an average of several instantaneous values over a period of time (called a "time constant") provides a more accurate measurement. This average is updated once per second and is therefore a moving average calculation. The Q-Trak Plus monitor is shipped new from the factory with a default "time constant" setting of one minute. The time constant is the window of time over which the instantaneous values are averaged. For example, with a time constant setting of 10 seconds, the current measurement is the average of all instantaneous values over the previous 10 seconds. The time constant setting is user-selectable between 2, 5, 10, 15 and 30 seconds and 1 minute. This allows the user to adjust the time dampening effect on the real-time display in the survey mode. As the time constant setting is increased, more "smoothing" of the instantaneous values occurs. For IAQ measurements like temperature, humidity, CO2 and CO, the one minute setting works very well. There may be cases, such as when making velocity measurements with the air velocity probe accessory, where the user may want to reduce the dampening or time it takes to record a specific sample. This can be done by setting the time constant to a smaller value. To change the time constant setting, enter the main menu of the Q-Trak Plus monitor and highlight "time constant". Use the up/down arrow keys to select a setting between 2 seconds and 1 minute. For acquiring velocity samples, many users prefer a time constant setting of 5 to 15 seconds. TSI recommends re-setting the time constant to the factory default setting of 1 minute after completing your velocity measurements.

I have calibration quality CO2, but the concentration isn't exactly 1000 ppm. Will I be able to use it to calibrate the Q-Trak™ Plus IAQ Monitor?
Yes. The Q-Trak™ Plus IAQ Monitor allows you to enter the concentration of the calibration gas and will automatically calibrate to that concentration.
I like the portability of the Q-Trak™ Plus IAQ Monitor, but I am concerned about the possibility of tampering or theft during unattended monitoring.
The Q-Trak™ Plus IAQ Monitor is equipped with an inconspicuous display/keypad lockout switch which prevents unauthorized or accidental tampering during unattended operation. To prevent theft, some customers have hidden the main body of the instrument in the area above a suspended ceiling with the probe hanging down. Other ideas include a file cabinet, locked box, drawer, or other secured area.
I'm not a computer expert. What is the easiest way to understand the TrakPro software?
TrakPro software includes example data files. These files contain test examples useful for learning how the software operates independent of the instrument.
Is CO2 dangerous at a concentration of 800 or 1000 ppm?
No. CO2 concentrations above 800-1000 ppm are an indication of insufficient fresh air supply in a building's HVAC system and may result in reduced occupant comfort and efficiency. Lack of proper ventilation is often associated with the accumulation of other pollutants which may have more harmful effects on building inhabitants.
Is it possible to change the temperature readout between Fahrenheit and Celsius?
Yes. Simply highlight TEMP using the up and down arrows. Then use the left or right arrow to toggle between fahrenheit and celcius.
Is it possible to improve the response time of the temperature sensor?
Yes. Waving the probe to increase air flow through the sensors can significantly improve the response time.
Is it possible to lengthen the cable between the probe and the instrument?
No. Lengthening the cable would cause a decrease in instrument accuracy.
Is the CO sensor life affected by temperature and humidity?
Temperature - The operating life of the CO sensor is not greatly affected by temperature when kept within the rated operating temperature range. Prolonged operating or non-operating exposure to temperatures outside the rating may damage the sensor.Humidity - Continuous operating or non-operating exposure (months) to humidity above 90% can cause damage to the sensor. Continuous operating or non-operating exposure (months) to humidity below 10% can shorten the life of the sensor.

What is the difference between the Q-Trak™ Indoor Air Quality Monitor Model 8552 and Model 8554?
The Q-Trak™ IAQ Monitor Model 8554 also measures CO levels.
What is the expected CO2 sensor life?
The sensor should last for many years barring physical damage. There are no membranes or elements which might fail and require sensor replacement. In the unlikely event of sensor failure, other instrument sensors are unaffected.
What is the expected life of the CO sensor?
Although electro-chemical sensors often last for many years in a laboratory environment, exposure to certain field conditions may reduce life to 2 years or less. Sensor life may be reduced by low or high humidity, dust, or oil vapors. The most common signs of sensor degradation are indicated by drift in the zero reading or by inability to calibrate successfully. Despite its variable life, the electro-chemical sensor remains the best method of measuring low levels of carbon monoxide in a practical portable instrument. For this reason, TSI has chosen to develop, manufacture, and provide an electro-chemical sensor for this application. In the event of CO sensor failure, other instrument sensors are unaffected.
What is the expected life of the temperature and humidity sensor?
Both sensors should last for many years barring physical damage. There are no membranes or elements which might fail and require sensor replacement. In the unlikely event of a sensor failure, other instrument sensors are unaffected.
What is the warm-up time of the Q-Trak™ Indoor Air Quality Monitor?
When the Q-Trak™ Indoor Air Quality Monitor is first turned on, it takes about a minute for the instrument to settle down to a stable reading. When taking measurements from one area to another, stable readings can be obtained in 20 seconds. If there are significant variations in temperature from one area to another, it may take up to five minutes for a stable temperature reading.
What is the warranty period of the CO sensor?
The warranty for the CO sensor is two (2) years.
What levels of CO are considered dangerous?
Health Effects Of CO Exposure At 10 ppmFatigueAt 25 ppm for 24 hoursVision impairmentAt 50 ppm for 24 hoursHeadache and irregular heartbeatAt 500 ppm for 1 hourNausea and mental confusionAt 1500 ppm for 1 hourMay lead to death
What type of battery is used in the Q-Trak™ Plus IAQ Monitor? How long will they last?
The Q-Trak™ Plus IAQ Monitor is shipped with four standard size AA alkaline batteries required for operation. Alkaline batteries will provide about 13.5 hours of operation. NiCd batteries may be used in the Q-Trak Plus monitor, but must be recharged in an external charger provided by the user. Operating time using fully charged NiCd batteries will be about 4.75 hours.
Why are two CO2 calibration kits available from TSI (1000 ppm and 5000 ppm)?
Most people interested in indoor air quality calibrate at about 1000 ppm since the primary range of interest is between about 500 ppm and 1000 ppm. The 5000 ppm calibration kit is available for people interested in maintaining the highest possible accuracy when measuring higher concentrations.
Why during battery charging operations does the carbon monoxide sensor show high carbon monoxide readings?
Most rechargeable large commercial or industrial batteries used are lead acid batteries. These batteries are used in forkifts, golf type carts, etc. When charging these lead acid batteries hydrogen (H2) gas is produced. Hydrogen gas is a by-product from the electrolysis reaction (charging) of the lead acid battery. Hydrogen gas can interfere with the carbon monoxide sensor. The carbon monoxide sensor is sensitive to and will respond to hydrogen gas at about a 10 to 15 % of it's actual concentration. If you find you are getting high carbon monoxide readings around battery charging operations do not be alarmed, but be cautious. The Lower Explosive Limit (LEL) for hydrogen 4.0 % by volume (40,000 ppm by volume).
Will the CO sensor deteriorate while in storage?
While in the original package, the usable life of the CO sensor is unaffected by storage. Once the sensor is removed from the package and put into service, the total usable life of the sensor includes the operating and non-operating time.
Will the instrument measure temperature or humidity in an air stream?
The temperature and humidity sensors are designed to allow measurement in moving air or still air. No special procedures are required.
