This product adopts international advanced gas sensing technology, the use of high performance-cost ratio of imported microprocessor core as control, embedded specialized processing software that detects leaks concentration at the same time, you can monitor the sensor failure, has the extremely high security and reliability. When the alarm detection into the environment of the concentration of combustible gas reaches or exceeds a preset alarm value, the alarm sound and light alarm immediately issued to advise us promptly take security measures to prevent poisoning, explosion and fire, thus protecting life and property safety.
Features:
◆ The microprocessor control
◆ Automatic reset
◆ High stability sensor
◆ Automatic fault detection function ◆ SMT process
◆ Joint manipulator, solenoid valve, exhaust fan
◆ Detection of natural gas, liquefied petroleum gas, city gas
