KEY FEATURES
•
Electrochemical sensor measures real-time formaldehyde
gas concentration from 0 to 5 ppm with ±5% accuracy and

average), 1-hour average, and 15-minute STEL (short-term
exposure limit)

One-button calibration to 0 ppm in fresh air
•
User-adjustable high concentration audible alarm threshold

Also measures relative humidity (RH) and temperature in
°F or °C
•
Manually offsetable long-term drift of temperature and RH
accuracy
