Product Description

Description

S350AS portable laser gas telemetry instrument is composed of optical machine system, signal processing system, display and alarm system and shell components.Mainly used for remote measurement of methane or methane gas (natural gas, gas or similar gas) concentration.
The telemeter sends an infrared laser to the detection point, which can quickly measure the concentration of air mass between the detection point and the telemeter.To facilitate observation, the telemeter also fired a visible red laser to the detection point.The telemetry instrument can detect the methane concentration value of the detected location in real time and accurately, display and store the methane concentration value. If the alarm value exceeds the value, the acousto-optic alarm will be given, so that the personnel can make subsequent disposal.
Detection principle
The measuring principle of the telemetry instrument makes full use of the absorption characteristics of methane gas to a specific wavelength. When the detection beam encounters methane molecules, part of the detection beam will be absorbed by methane molecules. By measuring the absorption rate, the concentration of methane gas mass distributed between the target point and the telemetry device can be known.
