Description
Overview
GAOTek methane gas leak detector is specially designed with advanced TDLAS technology, for fast and remote detection of underground pipelines, lofts, green belt, gas plant etc., giving fast response and high resolution. accuracy. The light at this wavelength is only absorbed by methane, so it only reacts to methane and is not affected by other gasses, which greatly improves the accuracy of detection. Using the Remote Methane Leak Detector, the operator does not need to be in a dangerous environment, which not only protects the safety of the inspector, but also can inspect the overhead pipeline from a long distance, which improves the inspection efficiency.
 Features

- Detection distance maximum 80 meters
- Visual and audible alarm
- GPS location function, data transmitted to monitoring platform by GPRS
- High selectivity, only response to methane
- Fast response, no alarm delay
- High sensitivity, no interference from vapor, car exhaust and other gasses
