Electrochemical sensor. 🔬DETECT: Electrochemical cell sensor with error: ≤ ± 5% F.S. and response time: < 30 sec. Zero and span calibration options. Comes factory-calibrated. 🎆 ALARMS: Adjustable audio, visual, and vibration alarms alert when preset levels are reached. 💪 STRONG: Shockproof, water-resistant, dustproof, and explosion-proof with belt clip. 🕵️ TRUSTWORTHY: 1-year limited warranty. Arrives with a signed and dated calibration certificate. Details: The professional OZONE O3 gas detector + pump (0.5 LPM) by FORENSICS is the best in its class with all advanced features and functions. The detector and pump setup is used to perform point or continuous sampling in remote locations. Be attentive to ozone, it decays quickly so keep the tubing as short as possible. Also, ozone cannot be calibrated with a gas bottle. 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 calibrated equipment necessary to perform ozone gas detector calibration. Included: Gas detector, user manual, computer USB charging cable, calibration cover, and certified calibration certificate. The pump unit comes with the pump, stainless probe, 3 ft silicone tubing, USB charging cable, and user manual. Calibration Options: Calibration Service by Forensics Detectors 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.
