Oxygen concentration meter WatchGas 7192002 1 piece

The WatchGas PDM+ Oxygen Concentration Meter is a gas detector that can detect oxygen in the environment. When turned on, it continuously measures oxygen levels and alerts you to dangerous conditions with an alarm using LEDs, vibrations, and a buzzer. The sensor and battery have a lifespan of approximately two years, and the sensor can be replaced, calibrated, and the battery replaced. It is easy to operate, and there is a metal clip on the back of the main unit, so you can attach the main unit to a shirt, belt, helmet, etc. Measurement target: Oxygen (O2) Measurement range: 0 to 30% Sensor usage period: Approximately 2 years Battery life: Approximately 2 years Dimensions (W x H x D): 48 x 85 x 22 mm Weight: 104g Operating temperature: -35 to +50°C Operating humidity: 5 to 95% RH (no condensation) Alarm: Electronic sound 95dB@30cm, red LED, vibration Measurement method: Diffusion type Material: Body: Polycarbonate, rubber Explosion-proof certification ATEX: II 1G Ex ia IIC T4 Ga IECEx: Ex ia IIC T4 Ga Accessories: Instruction manual, calibration adapter, calibration certificate (test report) Calibration certificate: included Resolution: 0.1% Measurement principle: Electrochemical Power supply: Lithium battery 3.6V 1.2Ah Protection rating: IP67 Applications: Preventing oxygen deficiency, preventing oxygen deficiency, tanks, reaction towers, ship holds, wells, manholes, pits, underground, etc. RoHS2 (EU)2015/863 compliant [About RoHS]
