LI-COR CO2 Gas Analyzers

Some CO₂ sensors are too simple. Other CO₂ analyzers are costly and complex. But the LI-830 and LI-850 from LI-COR Environmental are just right—bringing proven performance at an economical price to provide CO₂ gas measurements that you can depend on day after day.

Two Levels of Accuracy: LI-830 (CO₂-only) or the LI-850 (CO₂/H₂O) 

The LI-830 measures CO₂ in air with an accuracy of 3%. The LI-850 measures both CO₂ and water vapor in the air, so it can account for band-broadening due to water vapor. This allows reporting of CO₂ concentrations with an accuracy of 1.5% .These analyzers are ideal for atmospheric air measurements and many general-purpose applications, with a CO₂ measurement range of 0 to 20,000 ppm, H₂O measurement range of 0 to 60 mmol/mol (LI-850 only), and output rate of 2 measurements per second (2 Hz). Using either the USB, serial, and analog outputs, you can offload your data to a personal computer, data logger, or your own data recording device, such as an Arduino®.

Low power requirements and their light weight also make these ideal for remote, mobile, and battery-powered deployments, including use with weather stations. The wide operating temperature range and onboard temperature measurements ensure consistent performance—even if ambient temperature changes rapidly.

The LI-830 and LI-850 are available with an optional pump for an out-of-the box flow solution and an optional display to view measurements in real time without a computer or datalogger. All LI-830 and LI-850 gas analyzers feature configurable alarms when a CO₂ or H₂O threshold is crossed.

Application Versatility

Whether you are monitoring ambient CO₂ concentrations, controlling a process, or measuring CO₂ for an experiment, these small, light analyzers deliver high-quality measurements and data you need for many applications:
