The JT-AT2004A / JY-AT2004A Series is an intelligent household combustible gas detector providing all-round family safety protection. Equipped with advanced temperature compensation, it adjusts detection parameters according to ambient temperature changes, avoiding false/missed alarms for natural gas and LPG. It has an automatic lifetime expiration reminder to prompt timely replacement. Supporting wireless solenoid valve connection, it cuts off gas sources quickly when leakage occurs, with clear valve status indication. A built-in black box records alarms, faults, and logs for maintenance. Unique in supporting NB-IoT/4G CAT1, it enables remote gas status monitoring via mobile devices. Made of V0-rated flame-retardant material with IP31 protection, it resists dust and light water splashes. Compact, lightweight, and easy to install, it is an essential intelligent safety helper for modern households.
Advanced temperature compensation adjusts parameters dynamically to prevent false and missed alarms.
Wireless solenoid valve connection shuts off gas sources instantly upon detection of a leak.
Supports NB-IoT and 4G CAT1 networks for real-time remote gas status monitoring via mobile devices.

Detects low-concentration gases with noticeable changes in electrical signals.
Rapid alteration of semiconductor electrical conductivity upon gas adsorption enables quick detection.
Detects most volatile organic compound (VOC) vapors effectively.
Simple structure, low manufacturing cost, and stable long-term performance, making it suitable for cost-sensitive scenarios.
The detector is designed to monitor combustible gases, specifically CH4 (Methane / Natural Gas) and C3H8 (Propane / LPG).
It features advanced temperature compensation technology that dynamically adjusts the detection parameters in response to changes in the ambient temperature.
The device triggers sound and light alarms, sends output signals (relay or solenoid valve output), and can wirelessly trigger a connected solenoid valve to cut off the gas source immediately.
Yes, the device supports NB-IoT and 4G CAT1 networks, enabling users to check and monitor the real-time gas status remotely via mobile devices.
The typical lifespan of the detector is 5 years. It is equipped with an automatic lifetime expiration reminder that prompts you when it is time to replace the unit.
