Freestanding combustible gas alarm, using the international advanced gas sensing sensing technology, the choice of cost-effective microprocessor as control core, is a security product for small gas used in the home, for continuous detection of indoor gas leak concentration, when the leak concentration reaches the set value, the detector audible alarm. When the indoor gas concentrations below the alarm set value, the detector automatically return to normal working condition, can avoid poisoning combustible gas leak caused an explosion, fire or other personal injury, property damage accidents.

Features
1. Using high-quality semiconductor heat sensor, good stability.
2. MCU intelligent control to monitor, SMT placement process
3. Having a live sound and light alarm.
4. Digital display technology, display real-time leak concentration.
5. Three kinds of directions: power indicator -POWER, status indication -STATE, alarm indication -ALARM.
