Comfort Chek™ 500 Portable Air Quality Monitor
Comfort Chek™ 500 is an affordable, easy to use indoor air quality (IAQ) monitor designed with three
sensors that simultaneously measure and record temperature, relative humidity, and carbon dioxide
(CO
2
) levels in the air. It can collect up to 26,000 data points and store them in its internal flash memory.
The large, backlit LCD displays all three sensor readings as well as battery status and provides easy
readability in dark environments. Powered by alkaline batteries or with supplied wall adapter.
• Automatically calculates and displays MIN,MAX, STEL and TWA values for CO
2
• Quick and easy calibration for CO
2
and RH
• Offers around the clock air quality monitoring in office environments or public facilities
IEQ Chek™ Indoor Environmental Quality Monitor
IEQ Chek™ is a versatile multi-sensor instrument for measuring, monitoring and recording indoor
environments for air quality diagnosis. With its 7-sensor capacity, the new IEQ Chek™ measures
temperature, relative humidity, and up to 5 additional plug-and-play ‘smart’ sensors, including carbon
dioxide (CO
2
), carbon monoxide (CO), oxygen (O
2
), formaldehyde (HCHO), total volatile organic
compounds (TVOCs), nitrogen dioxide (NO
2
), sulfur dioxide (SO
2
), ammonia (NH
3
), hydrogen sulfide
(H
2
S) and combustible gases. Large multi-line backlit LCD display with simultaneous viewing of all
installed sensors, battery life, pump indicator and calibration status.
• Versatile handheld instrument with flexible 7-sensor capacity
• Ideal for indoor environmental quality measurements
• On-board sensors for temperature and relative humidity; add up to 5 additional
plug-and-play 'smart' sensors - available with on-board pump for sampling air
• Stores over one million data points with SD flash card
