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.

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