TDLAS200 Portable Methane Gas Detector

1.Introduction

The KACISE TDLAS200 Portable Methane Gas Detector is a lightweight and user-friendly device for on-site methane detection. With a fast response time of 0.1 seconds and a detection range of 0~5000ppm, it ensures accurate and reliable measurements. Its compact design and digital interface make it easy to operate in the field. The detector is built to withstand harsh conditions, with an operating temperature range of -20~50℃. KACISE delivers a portable and efficient solution for professionals in environmental monitoring and industrial safety.

2.Features

1. High sensitivity, only responds to the target gas
2. Built-in reference cell, can be automatically calibrated
3. Easy to integrate, digital interface directly outputs status and concentration

3.Measuring Principle

"Methane molecules absorb light of a specific wavelength" --Molecular absorption spectrum
"The amount of light absorbed by a transparent medium (methane gas mass) is proportional to the thickness and concentration of the gas mass" --Beer-Lambert's law
According to the above physical principles, a beam of light of a specific wavelength can be used to penetrate the leaking methane gas mass. According to the degree of weakening of the beam, the concentration of methane in the gas mass can be measured, and it only responds to methane (unique selectivity).
Using a detection cell with multiple reflections and allowing the laser to repeatedly pass through the gas being measured can multiply the detection sensitivity.
