Overview

A better choice for rapid eddy covariance flux measurement and soil flux research.

Product Details

LGR (currently under ABB Canada)The Rapid Methane Analyzer（FMA）Easy to operate, low power consumption, sturdy and durable, it is an ideal tool for field monitoring of methane. Quick measurement（20 Hz）Its characteristics make it a better choice for vortex related covariance flux measurement and soil flux research.

FMADesigned for various purposes, including vortex related flux measurement using micro meteorological technology, chamber method flux measurement, and natural gas pipeline leakage inspection, it has the characteristics of high accuracy and fast response. The analyzer is not affected by interference from other gases in the atmosphere (no cross interference), nor is it affected by changes in atmospheric pressure (no pressure broadening effect).LGRThe uniquely designed "dynamic dilution system" option canCH₄Range extension100Multiple times or more, and ensure that the accuracy and sensitivity are consistent with measurements taken at typical environmental levels.

FMAuseLGROutput spectrum of off-axis integrating cavity with patented design（OA-ICOS）Technology (patent number: 6795190), which eliminatesCRDSDuring the measurement process, technology requires continuous matching of the optical cavity and laser wavelength to improve the weak signal intensity, eliminating the need for complex laser alignment adjustment, temperature control, and wavelength monitoring in the analyzer. Real time display of high-resolution laser absorption spectra. Using a built-in computer（Linux OS）To provide continuous storage and measurement of data. With remote control function, users can operate the analyzer from any location through the network, and can also share real-time data and perform instrument diagnosis through remote login.
