Ambient Air Quality Monitoring Instruments for Outdoor CO Gas Concentration Detection
Product Introduction
The carbon monoxide analyser is an analyser that measures CO at the ppm level by comparing the intensity of the infrared light absorbed by a sample gas with that of a reference gas, based on the Beer-Lambert law. It is one of the analysers used in ambient air quality monitoring systems to measure CO concentration levels in ambient air quality parameters.
Product Performance
3. Adaptive filtering optimises response time
4. It supports remote calibration and parameter diagnosis;
5. Built-in memory can store average data of three months;
6. Optional multi-ranges are optional;
7. It has the function of multi-parameter alarm;
