2021 China New Design Dahua Dome Camera 4k - Hand-held laser remote methane gas leak detector(JJB30) – Topsky

1.Overview
Hand-held laser remote methane gas leak detector is a high-tech advanced technology that detects methane leaking from long distances.It is a new generation of leak detection products, which greatly improves the efficiency and safety of walking inspection, the instrument available, widely recognized worldwide.
It uses tunable laser spectroscopy (TDLS) to quickly detect gas leaks up to 30 meters away.People can effectively detect hard-to-reach or inaccessible areas within safe areas, such as busy roads, dangling pipelines, tall towers, long haul pipelines, unattended rooms and more. Its use is not only effectively improve the efficiency and quality of walking inspection, but also makes easy which can not reach or difficult to reach the place of inspection possible.
It is lightweight, low energy consumption and can support long-term continuous measurement tasks and can adapt to a variety of environmental needs (such as a wide range of operating temperature and pressure, high humidity, etc.). This product has a sensitive detection reaction ability, just 0.1 seconds to get the test results, detection accuracy up to 100ppm-m or even lower and also could be customized according to customer data transmission methods, such as Bluetooth.

2.Features
