Point-type Laser Natural Gas Leakage Detector
1.Product Overview
The point-type laser natural gas leakage alarm device Discovery-PA1
is based on the advanced laser absorption spectroscopy (TDLAS)
principle and can conduct real-time and accurate monitoring of
natural gas leaks.
2.Product Features

lasers
(2) High selectivity, only reacting with methane and unaffected by
other gases
(3) Digital display of gas concentration and working status
(4) Strong corrosion resistance, long service life, high precision,
low drift, fast response, low power consumption, stable and
reliable operation
(5) Automatic zero-point calibration function, single-point
calibration, convenient for maintenance
(6) Temperature compensation is available
(7) Equipped with an intelligent monitoring and data management
system, which can monitor and store data in real time on the
background
(8) Suitable for various complex and harsh environments
(9) Installation process is simple and fast, no need for complex
wiring and debugging
(10) Sealed explosion-proof design is suitable for hazardous
conditions 1 and 2
(11) No calibration required, no maintenance needed
3. Application
It can be widely applied in industrial and commercial facilities,
such as comprehensive pipeline tunnels, petroleum, chemical, steel,
fire protection, power, environmental protection, and
pharmaceutical industries.
