  • 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: -- Constituent / Typical Concentration in Ambient Air = Alcohol / <1 ppm; Ozone / <0.1 ppm; Formaldehyde / <1 ppm; Solvents / <1 ppm; Hydrogen sulfide (H(2)S) / <1 ppm; Sulfur Dioxide (S(O)2) / <0.1 ppm. --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: --Chemical / Formula / CO Sensor Typical Response / TLV (ppm) / CO Sensor Response @ TLV (ppm) = Acetylene / C(2)H(2) / 100% / 100* / 100; Ammonia / NH(3) / <5% / 35 / <2; ALcohol / -- / <5% / 100* / <5; Carbon Monoxide / CO / 100% - 50 - 50; Chlorine / C(l) / <5% / 1 / 0; Formaldehyde / H(C)H(O) / <5% / 0.3 / <0.015; Hydrogen / H2 / 25% / 100 / 25; Hydrogen Chloride / HCl / <5% / 5 / <0.25; Hydrogen Sulfide / H(2)S / <5% / 15 . <0.75; Nitrogen Dioxide / NO(2) / <5% / 5 / <0.25; Sulfur Dioxide / SO(2) / <5% / 5 / <0.25. --*TLV not available.

  • How can non-USA customers get calibration gases?
    TSI is not able to ship calibration gases internationally. How to Obtain Calibration Gas in non-USA Locations TSI is not able to ship calibration gases internationally due to international transportation regulations. As such we provide a means for our international users to obtain calibration gases through local TSI distributors or directly from the specialty gas manufacturers. The information below contains the calibration gas and regulator specifications for the following TSI instruments;* Q-Trak™ and Q-Trak™ IAQ Monitors* InspectAir™ CO2 Monitor* IAQ-Calc™ Indoor Air Quality Meter (Models 8732, 8760 and 8762)* CombuCheck™ CO2 Meter* CA-Calc™ Combustion Analyzers (all models)* Q-Check™ CO2 and CO MetersAlso, a recommended listing of international gas vendors capable of shipping directly to distributors or users is included.Note: these calibration gases and accessories must be purchased directly from the listed vendors, not from TSI-USA; and that TSI-USA does not warranty, guarantee the quality or availability of these calibration gases obtained directly from these specialty gas vendors.Q-Trak™ IAQ Monitors use a 0.3 to 0.75 L/min regulatorSpan Calibration Gases * 1000 ppm CO2 in balance air** 5000 ppm CO2 in balance air* 35 ppm CO and 1000 ppm CO2 in balance air* 35 ppm CO in balance air* 200 ppm CO in balance airZero Gas * Zero Calibration Gas (air*) for CO2 and CO sensor calibration
  • How fast do the sensors respond to changes?
    Sensor Response Time CO220 sec1 Temperature30 sec2 Humidity20 sec2 CO<60 sec2 1 For 63% of final value for 500 ppm step change.2 For 90% of final value at an air velocity of 2 m/sec. 
  • How long is the warranty on the Q-Trak™ indoor air quality monitor?
    The Q-Trak™ indoor air quality monitor is warranted to be free from defects in workmanship and material for a period of twenty-four months from the date of shipment to the customer. Batteries and sensors are excluded from this warranty. See the Operation and Service Manual for complete warranty terms and conditions.
  • How many calibrations can be done with the TSI calibration kit?
    Each calibration uses a minimum of 1 minute of each gas (zero air and CO). 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 Q-Trak™ Plus indoor air quality monitor. The TSI calibration kit part number 8938 contains two cylinders to be used in calibrating both the CO2 and CO sensors in the Q-Trak™ Plus monitor w/CO. One cylinder contains zero air and the other contains both 35 ppm of CO gas and 1000 ppm of CO2 gas. The kit will provide 50-100 calibrations of the CO2 and CO sensors in the Q-Trak™ Plus indoor air quality monitor w/CO.
  • How should I dispose of empty calibration gas cylinders?
    Calibration gas cylinders supplied by TSI are disposable. You may be required to dispose of these cylinders as hazardous waste. Refer to local, state, or federal regulations.
  • 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 Q-Trak™ Indoor Air Quality Monitor intrinsically safe?
  • What are the measurement ranges of the Q-Trak™ Indoor Air Quality Monitor?
  • What happens if my batteries die during operation?
    Low battery charge is indicated by a battery symbol on the display. The Q-Trak™ Plus Indoor Air Quality Monitor will continue to operate for approximately 60 minutes before measurement and logging functions stop. Power will shut off automatically, but the logged data will be retained by an internal backup battery.
  • 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.
