Details: This is our Ozone (O3) gas meter by FORENSICS 0-20ppm. This ozone meter has a wide range of functions with the highest quality electrochemical sensor.  Ozone is a reactive gas and a well-documented air pollutant and irritant. The NIOSH recommended exposure limit for ozone is 0.1 ppm (0.2 mg/m3). The NIOSH immediately dangerous to life or health (IDLH) ozone level is set to 5 ppm or higher. This is a great generic ozone meter for a variety of uses. Please note that ozone is unique gas and cannot be calibrated with a calibration gas bottle setup like most gases. Order your ozone calibration service which must be performed in our laboratory with special NIST calibrated equipment necessary to perform ozone gas detector calibration. 

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