Details: The nitrogen dioxide (NO2) gas detector by FORENSICS has the most advanced features and functions for industrial applications, including an advanced electrochemical sensor. Nitrogen dioxide (NO2) is part of a group of highly reactive gases known as nitrogen oxides (NOx). NO2 is used as the indicator for the larger group of nitrogen oxides. Nitrogen dioxide primarily gets in the air from the burning of fuel. NO2 is formed from emissions from cars, trucks, buses, power plants, and off-road equipment. OSHA workplace exposure limits are set at 5 ppm over any period of time. The NIOSH REL is set at 1 ppm as a 15-minute short-term limit. ACGIH exposure limit is 3 ppm over 8 hours and/or 5 ppm short-term exposure. For those requiring point sampling or NO2 leak detection, you will need a NO2 analyzer with a built-in pump analyzer variation; in this case, we recommend our FD-600-NO2. Also, for those requiring a NOx analyzer, see our FD-600-NOx.
Included: Nitrogen Dioxide gas detector, belt clip, sling, user manual, USB charging cable, calibration cover, and certified calibration certificate.
