Strong anti-interference ability
It adopts advanced laser spectral analysis technology, which is responsive to methane and is not affected by temperature and humidity;
Millisecond response
Millisecond response time can greatly improve the efficiency and quality of user patrol inspection;
Ultra long distance telemetry
Ultra long distance telemetry makes it safe and convenient to inspect special and dangerous areas that are inaccessible or difficult to reach;
Simple operation
Only need to simply pull the trigger to easily detect without complex training;
LCD display function
Clear and intuitive LCD concentration display function (model C is color LCD display);
Maintenance free
Since the internal laser device and optical structure are relatively stable, generally no maintenance is required;
Long lifetime
The service life can be up to 5-10 years, and the comprehensive use cost is low;
Bluetooth communication
Built-in Bluetooth communication function, with mobile phone APP can realize the functions of patrol track recording, concentration curve, log reading, etc.
