Product Description：
The JTM-SSJ III-E Combustible Gas Detector is designed in compliance with China's national standard GB15322.2-2019. It provides alarms for gas concentration (exceedance), device faults, and service life expiration, with high-brightness concentrated LEDs of different colors for indication. The detector can detect single or dual gases (methane + carbon monoxide) and is suitable for monitoring gas leaks in residential natural gas pipelines.
Product Features：
※ Equipped with LED service life indication.
※ Features an alarm mute function.
※ Concentration and fault alarm indicators use high-brightness concentrated LEDs of different colors.
※ Adopts high-quality gas-sensing elements, with stable performance, high sensitivity, excellent anti-toxicity, and strong anti-interference capability.
※ High performance, low power consumption, simple operation, and easy maintenance.
※ IoT-enabled, with remote alarm information push via WeChat, platforms, and APPs .
※ It supports wired/wireless valve actuation, which reduces the difficulty of on-site wiring and enables more flexible installation.
