Details: This is an ultrasensitive OZONE detector with 0.01 ppm resolution. It is 10x more sensitive than a regular meter as it employs a high-quality ozone sensor made in Switzerland. Although ozone gas is used in many applications as a "sanitizing" agent, too much can be harmful. Ozone is a reactive gas and a well-documented air pollutant and irritant. The California Ambient Air Quality Standard (CAAQS) for outdoor ozone is 0.09 ppm for a 1-hour average and 0.07 ppm for an 8-hour average. OSHA guidelines state that ozone in the workplace should never exceed 0.1 ppm over an 8-hour day. NIOSH outlines a recommended exposure limit of 0.10 ppm (0.2 mg/m3) and an immediately dangerous to life or health (IDLH) ozone level of 5 ppm or higher. 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, sling, English manual, USB charging cable, calibration cover, and USA NIST calibration certificate.

Calibration Kit:
No ozone calibration gas kits exist for ozone since ozone gas (NIST traceable calibrated) must be generated in a special lab. We recommend using our calibration service to calibrate your ozone detector and using our ozone bump tester to validate operation via bump testing.
