Gas Analyzers

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
• Indoor and outdoor air quality monitoring
• UAV and drone-mounted CO₂  measurement systems

• CO₂  partial pressure (pCO₂ ) measurement systems
• Carbon sequestration studies
• Total Organic Carbon (TOC) measurement systems

• Process controls for manufacturing
• Custom machine builders, system integrators, value-added resellers, or equipment manufacturers that seek to integrate a gas analyzer into a product
• Volcanology studies
• Atmospheric profiling systems
