Overview
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 Precision: LI-830 (CO2-only) or the LI-850 (CO2/H2O)
The LI-830 measures CO2 in air with a precision 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 that allows reporting of CO2 concentrations with the precision 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:
- Greenhouses, controlled environment agriculture, growth chambers, and grow rooms
