Extech FM300 Desktop Formaldehyde Monitor

Measuring Formaldehyde (CH₂O) concentration, air temperature and humidity with user-adjustable alarms, the Extech FM300 Desktop Formaldehyde Monitor is ideal for monitoring indoor air quality.

In addition to audible beeping alarms (default at 0.08ppm), the FM300 offers both visibly bright LEDs and three facial icons to indicate indoor CH₂O warning levels, ensuring ease of use.

Designed with an electrochemical CH₂O sensor capable of measuring CH₂O from 0.00 to 5.00ppm, the Extech FM300 offers a Min/Max value recall function and is capable of calculating statistical weighted averages of TWA (8-hour Time Weighted Average) and STEL (15-minute Short Term Exposure Limit), making it an incredibly versatile monitor.

Alongside a CH₂O Calibration function in fresh air, the Extech FM300 boasts an internal memory for manually storing up to 99 readings with a recall function and comes complete with Universal AC adapter (100V-240V) and multiple plug types (US, EU, UK, AUS).
