Comfort™ Chek 500

Product Information

Comfort Chek™ 500 is Bacharach’s new low cost and easy to use indoor air quality (IAQ) monitor and is designed
with three sensors that simultaneously measure and record temperature, relative humidity, and carbon dioxide
(CO₂) levels in the air. The large LCD displays all three sensor readings as well as battery status and is backlit for
easy readability in dark environments. This essential monitor collects up to 26,000 data points and stores it in the
internal flash memory. Users can download the data through a USB port for analysis with Bacharach’s IQ Chek™
software. Comfort Chek™ 500 operates up to 24 hours with alkaline batteries, or the supplied wall adapter is
ideal for around the clock air quality monitoring in office environments, schools, hotels or other public buildings.
