The standalone combustible gas detector C2 with a measuring range of 0~100% LEL is an intelligent monitoring device for natural gas and petroleum liquefied gas. When the monitored gas concentration reaches a dangerous value, an alarm sound and a red warning signal will be issued. The gas leakage information is timely, promptely sent out.

The independent combustible gas detector JT-KBC2,measuring 0~100%LEL, is an intelligent monitoring device for natural gas and liquefied petroleum gas. The alarm and red warning signals will be issued once the concentration of the monitored gas reaches a dangerous level due to leakage and other reasons. Ensure that gas leakage information is transmitted promptly and without dead ends,while closing the solenoid valve, cutting off the leakage source and protecting the user's family safety.
