PRODUCT DESCRIPTION
Once activated, the sensor periodically reports the fire extinguisher's temperature, gas pressure, battery level, and obstruction status. It can also actively send alerts for abnormal temperature, motion, pressure, obstruction, or low battery to support real-time monitoring and proactive safety. Device parameters can be configured and firmware upgraded through the reserved user interface. Powered by a 2000mAh rechargeable lithium battery, the sensor offers a typical battery life of up to 2 years. Operating temperature: -20 to 70°C. The product features an ABS housing and copper fittings, designed for threaded installation on fire extinguishers.
