CruzPro GD20B Gas Vapor Monitor detects gas vapors at 10%, 20% or 30% of the concentration required for an explosion (LEL or Lower Explosive Limit).
The GD20 uses new technology to lower the power requirements for the sensor and the GD20 can be programmed to put itself to sleep for further power conservation.
The GD-20 Gas Vapor Detector can be programmed to be active continuously or wake up every 5 minutes for a sniff. If the GD-20 senses a dangerous concentration of gas, it sounds the alarm, cuts power to the LPG solenoid and deactivates sleep mode to continuously monitor the situation.
