Low Power Consumption Combustible Gas Detector

The HM-713 series low power consumption combustible gas detector takes advantage of high-sensitivity semiconductor sensor and microprocessor controller. It shows strong alarm sensitivity and conformability. The product is designed with ceiling installation mode. Its base can connect with the 86×86mm junction box. Meanwhile, the product can provide the manual testing and automatic reset functions.

The low power consumption combustible gas detector can detect the natural gas and liquefied petroleum gas. With the fault automatic diagnosis indication available, if the product has the problem, the yellow LED indicator would give the indication to notify the user of the situation. Additionally, the product is up to the standard of GB15322.2-2003.
