Product Details

Ultrafine (UFP) particles are everywhere- polluting the air, eroding our health, and affecting our climate; the first step in cleaning the air of these potentially hazardous particles, is to measure them. The  Environmental Particle Counter™ 3783 (EPC Monitor), the latest water based condensation particle counter (WCPC), a specific type of CPC, from TSI, can help.

EPA and European Commission reference methods (PM2.5, PM10), as well as equivalent mass based methods, cannot quantify the amount of UFP in the air; but the Model 3783 from TSI provides quantitative fine and UFP concentration data accurately and reliably where FRM and equivalent methods fall short.

The EPC™ monitor was born out of a methodical evaluation of the challenges specific to water based condensation particle counters used in high concentration environments. Newly designed air flow, wicking, and water handling systems provide superior accuracy, reliability, and ease of operation. Equipped with Aerosol Instrument Manager® software for comprehensive statistical analysis, on-board instrument diagnostics for easy troubleshooting, and multiple data acquisition options, data can be accessed and analyzed immediately both onsite and from remote locations.

After extensive customer feedback, rigorous internal testing, and thorough field validation, the 3783 boasts over 20 new product features ideal for long term, 24/7 monitoring in both pristine and heavily polluted environments.

FAQs
  • Can the CPC be operated with different carrier gases?
    Yes, but only inert gases.
  • How does the water CPC performance compare to CPCs that use butanol?
    Laboratory and field tests show excellent agreement and correlation between the water CPC (Model 3785) and butanol CPCs (Models 3010, 3025A and 3022A) for particles larger than about 20–30 nm. Preliminary test results can be viewed in a poster presentation by S. Hering, M. Stolzenburg, F. Quant and D. Oberreit (2003 AAAR Annual Conference, Anaheim, CA) at www.quanttechnologies.com. Additional test data will soon be submitted for publication.
  • How frequently should I have the CPC serviced?
    We recommend the CPC be returned for annual maintenance service. Your company’s Quality Management System may specify a more or less frequent service interval based on history, use and criticality of the measurement. The Standard Annual Service includes:Perform an ‘AS FOUND’ operational and calibration check.Replace tubing, o-rings and water wick.Clean optics, flow path and all wetted parts.Update firmware/software.Perform operational check.Calibrate flows.Calibrate photometric mode using sodium chloride aerosol.
  • How pure does the water need to be?
    We recommend using water that is distilled or purer. 
  • How sensitive is the instrument to flooding?
    While fairly insensitive to flooding, several precautionary measures will help avoid this condition. Do not tip the instrument more than 10 degrees in any direction. Avoid large pressure fluctuations or restrictions in flow at the sample inlet (>25 cm water at 1.0 liter/minute). When accessing the reservoir for cleaning or drying, always lay the instrument on its side with the Fill and Drain connectors on the bottom. 
  • Is the counting efficiency for each CPC determined individually?
    No. The CPC efficiency curve has been determined by testing a statistically valid number of CPCs and averaging the results to obtain the curve published in the product literature. Variation between units is very small.
