Description
Overview
GAOTek Laser Methane Gas Detector is composed of an optical-mechanical system, a signal processing system, a display and alarm system, and a shell assembly. It is mainly used to measure the concentration of methane or methane-containing gas (natural gas, gas or similar gas) from a long distance, and can be widely used for rapid positioning and detection of gas pipeline networks. LAser methane telemeter emits a beam of an infrared laser to the detection point, which can quickly measure the air mass concentration between the detection point and the telemeter. For the convenience of observation, the telemeter also emits a visible red laser beam to the detection point at the same time. The telemeter can detect the methane concentration value of the checked location in real time and accurately, and display and store it. When the alarm value is exceeded, it will give an audible and visual alarm so that personnel can make follow-up treatment.
Features
- Miniaturized design, easy to carry, life span of up to ten years
- Fast response in milliseconds, greatly reducing inspection time and improving work
- PPM level high sensitivity, gas leakage caused by early screw loosening
- On contact detection, especially suitable for areas that are difficult for people
- It can be detected through glass, which has better protection for personal safety
- Fingerprint characteristics, the only response to the measured gas
- Will not be poisoned or drift, greatly increase the service life of the product
