JT-CA319G series home combustible gas detectors redefine home gas safety.
Intelligent protection, safe and secure gas supply – JT-CA319G series laser home Combustible Gas Detectors launched globally.

Key Highlights: One-time installation, five years of peace of mind
Traditional Household Gas Detectors generally use catalytic combustion sensors, which have a short lifespan (usually 1-3 years) and are easily affected by kitchen fumes and alcohol, resulting in frequent false alarms or malfunctions that greatly trouble users. The JT-CA319G series was created to end this situation.
This product series utilizes advanced tuned laser spectral absorption technology , detecting methane molecules by precisely identifying their absorption spectrum. This fundamentally avoids cross-reactions with gases such as alcohol and cooking fumes, achieving exceptional reliability with zero false alarms . Furthermore, the laser sensor consumes no chemicals and has a theoretical lifespan far exceeding that of traditional components. The product's rated five-year lifespan provides users with long-term, stable safety assurance, significantly reducing maintenance costs and hassles associated with future replacements.
Intelligent linkage to build a proactive security defense line
The JT-CA319G series is not just a detector, but the core of an intelligent safety system. It features a built-in DC12V pulse signal output that can directly trigger an emergency shut-off solenoid valve , automatically cutting off the gas supply at the moment of alarm, thus preventing danger at its source. An additional set of passive switching signals can immediately activate the exhaust fan, accelerating the dissipation of leaked gas.
In addition, the product supports optional wireless transmission modules , allowing seamless integration with the company's IoT platform and wireless solenoid valve controllers. Users can receive alarm information in real time and remotely view device status via a mobile app, achieving comprehensive and multi-dimensional home gas safety protection from local audible and visual alarms to remote intelligent monitoring .
Robust design, adaptable to complex home environments
Designed specifically for complex home kitchen environments, the casing is made of anti-static ABS material , ensuring durability and safety. It operates in a wide range of environments (-10°C to 55°C, humidity ≤95%RH) with a power consumption of only ≤3W, making it a product truly designed for stable, long-term, all-weather operation.
