Overview

The online methane detector is a key project achievement of national environmental monitoring. It adopts the laser sensing principle of * to achieve online monitoring of methane gas, and has the characteristics of fast, accurate, and stable. This product can be widely used for gas safety monitoring in landfill gas power plants, petrochemicals, coal mines, and other scenarios, and can achieve remote data transmission.

Product Details

Online methane detectorProduct advantages:

Core technology control, using laser sensing core technology, with outstanding advantages of "fast", "accurate", and "stable";

Adopting the laser principle, it has the characteristics of no drift, long-term stability without calibration, and longer service life compared to the traditional infrared principle;

Calibration service, free calibration service, customers do not need to purchase standard gas;

Multi level pretreatment measures effectively filter impurities and water vapor, and include automatic drainage function, resulting in longer product service life;

PLC control output, capable of integrating multiple functions;

Multi channel integration enables multi-point integration testing solutions, facilitating on-site multi-point parameter testing and saving costs;

Large capacity data storage, with functions such as historical data storage, query, and export;

High cost performance solution, advantages of mass production and low cost, intentional damage caused by non-human factors, free replacement during the warranty period, and service provided at low cost price outside the warranty period;

Multi parameter measurement, simultaneous measurement of gas composition and humidity scheme, as well as supporting technology upgrades to display flow rate, etc;

Large capacity historical data storage, capable of storing data for up to 15 years.
