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.

Included: NO2 gas detector, belt clip, sling, English manual, USB charging cable, calibration cover, and USA NIST calibration certificate.
