Product Details

Handheld laser methane detectorTGS-CH4-UProduct Features:

Technical principle of laser methane detector: The laser methane detector is a technology principle based on tunable semiconductor laser absorption spectroscopy (TDLAS);

The laser methane detector has the characteristics of being unaffected by environmental temperature changes and background gas interference, with high detection accuracy and fast response.

Handheld laser methane detectorTGS-CH4-UIt is a natural gas pump suction detection device based on laser absorption spectroscopy technology, which can measure methane concentration. Commonly used in natural gas field stations, urban gas security checks, gas concentration analysis, and other occasions.

Key Features:

1. Lightweight design, adopting a compact and simple structural design, exquisite craftsmanship, and convenient portability of the detector.

2. Real time online measurement of CH4 gas can be achieved, with human interaction LCD display function.

3. The lifespan can reach more than 10 years, and a single charge can last for more than 20 hours.

4. Stable and continuous operation, no need for periodic calibration after factory calibration, making application more convenient.
