Operating
Temperature
-40ºC to +65ºC/ -40ºF to +149ºF
Note: The detector display may become illegible at temperatures below -40°C, but the detector continues its gas monitoring
function. The display is not damaged and recovers when the temperature rises back above -20 °C.
Sensor operating temperature range is dependent on gas type. Please refer to the Sensepoint Technical Handbook for details.
Operating
