Overview

Synchronize the measurement of carbon monoxide, carbon dioxide, and water vapor concentrations at the environmental level to achieve excellent accuracy.

Product Details

LGR (currently under ABB Canada)Carbon monoxide/Simultaneous measurement of environmental levels using a carbon dioxide analyzerCO、CO₂andH₂OConcentration, applied in trace gas monitoring, vorticity related flux measurement, box method flux measurement, exhaust emission measurement and other fields. The analyzer is particularly suitable for field measurements and has been successfully installed inNASAofDC-8Aircraft used for measuring the atmosphere in the troposphere and stratosphere. The analyzer adoptsLGRBuilt in temperature control technology provides higher precision, accuracy, and smaller drift.

CO/CO₂The analyzer adoptsLGROutput 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.

characteristic:

1. Real time synchronous measurementCO, CO₂andH₂Oconcentration

2. Higher accuracy

3. 10 HzHigh frequency measurement

4. Using a mid infrared quantum cascade laser, the measurement is not affected by changes in gas concentration or pressure

5. Full range linearity, with a range exceeding the environmental level20More than double

6. No need for liquid nitrogen or water cooling
