Electrochemical sensors. Comes factory calibrated in Los Angeles, CA to a NIST Traceable source. Detection range of NO2 is 0-20ppm within 30 seconds at an accuracy of +/- 5% full scale. The detector has a DC3.7V Li battery 1500mAh that allows >24 hours of continuous use. Advanced features such as temperature detection, alarm recording, alarm setting, backlight high resolution LCD, calibration features and others are all included. Nitrogen Dioxide (NO2) is one of a group of highly reactive gases known as oxides of nitrogen or nitrogen oxides (NOx). NO2 is used as the indicator for the larger group of nitrogen oxides. NO2 primarily gets in the air from the burning of fuel. NO2 forms from emissions from cars, trucks and buses, power plants, and off-road equipment. Workplace exposure limits include OSHA exposure limits of 5ppm over any period of time. The NIOSH REL is 1 ppm as a 15-minute short-term limit. ACGIH exposure limit of 3ppm over 8 hours and/or 5ppm short term exposure. The Product includes the Gas Detector, English Manual, Computer USB data cable and Calibration Cover.
