Details: This is our high-range (0-100ppm) Ozone (O3) gas meter by FORENSICS. In some cases, high ozone detection is required, mostly for those using ozone for sanitizing. This unit has advanced features, a wide range of functions, and the highest-quality electrochemical sensors. The detector is USA NIST traceable and calibrated in Los Angeles. 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. For those that want to detect the output of an ozone generator, this is not the unit you should purchase. For ozone output detection, we recommend a 0-10,000ppm ozone detector (special order product) since ozone generators typically produce ozone much high than 100 ppm.

Included: High range ozone gas detector, belt clip, 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 our ozone bump tester to validate operation via bump testing.
