The #FD08 is ideal for measuring levels of gaseous formaldehyde (HCHO) as part of a workplace indoor air quality (IAQ) maintenance program. It can also spot-check a residential environment.
Features:
- The electrochemical sensor measures real-time formaldehyde gas concentration with accuracy and resolution that meet the U.S. National Institute for Occupational Safety and Health’s (NIOSH’s) acceptance criterion
- Also tracks, calculates and displays three cumulative formaldehyde gas metrics: the 8-hour TWA (time-weighted average), the 1-hour average, and the 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
- Manually offsettable long-term drift of temperature and RH accuracy
- Min/Max memory and data hold
- Large backlit dual-readout LCD
- °F/°C switch
- Auto power off (can be disabled)
- Tripod mount
