Other CO<sub>2<\/sub> analyzers are costly and complex. But the LI-830 and LI-850 from LI-COR Environmental are just right\u2014bringing proven performance at an economical price to provide CO<sub>2<\/sub> gas measurements that you can depend on day after day.<\/p><h5>Two Levels of Accuracy: LI-830 (CO<sub>2<\/sub>-only) or the LI-850 (CO<sub>2<\/sub>\/H<sub>2<\/sub>O) <\/h5><p>The LI-830 measures CO<sub>2<\/sub> in air with an accuracy of 3%. The LI-850 measures both CO<sub>2<\/sub> and water vapor in the air, so it can account for band-broadening due to water vapor. This allows reporting of CO<sub>2<\/sub> concentrations with an accuracy of 1.5% .These analyzers are ideal for atmospheric air measurements and many general-purpose applications, with a CO<sub>2<\/sub> measurement range of 0 to 20,000 ppm, H<sub>2<\/sub>O 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\u00ae.<\/p><p>Low power requirements and their light weight also make these ideal for remote, mobile, and battery-powered deployments, including use with <a href=\"\/node\/13881\" target=\"_blank\" data-entity-type=\"node\" data-entity-uuid=\"30aaf49b-c196-4b92-9ac0-0400454cf268\" data-entity-substitution=\"canonical\">weather stations<\/a>.

LI-8x0
LI-COR CO2 Gas Analyzers
Call 1-508-759-9500 to order
The LI-830 and LI-850 gas analyzers from LI-COR Environmental provide dependable, continuous carbon dioxide (CO2) measurements in a compact design. Choose the LI-830 for CO2-only measurements or the LI-850 for simultaneous CO2 and water vapor measurements.
Compare the LI-830 and LI-850
Both analyzers measure CO2 concentrations from 0 to 20,000 ppm. The LI-850 also measures water vapor and accounts for its effect on CO2 measurements, providing greater CO2 accuracy.

Flexible Data Collection and Integration
USB, RS-232 serial, and analog outputs allow you to record measurements using a computer, compatible data logger, or your own data acquisition system. Analog output options include 0–2.5 V, 0–5 V, and 4–20 mA.
Instrument software for Windows and macOS lets you configure the analyzer, view live measurements, and log data to a connected computer.
Choose Your Pump and Display Options
Both models are available with or without an integrated pump and display. Choose an integrated pump for a built-in gas flow solution, or a configuration without a pump for integration with your own sampling system. The optional display shows measurements without a connected computer or data logger.
Configurable alarms respond to CO2 thresholds and, on the LI-850, water vapor thresholds. See the Configuration Options section for model numbers and included equipment.
Compact Design for Flexible Deployments
Low power requirements and light weight make these analyzers suitable for remote, mobile, and battery-powered measurement systems. Onboard temperature and pressure measurements support consistent measurement performance as conditions change.
For outdoor deployments, select appropriate protection and sampling equipment for your installation. Review the analyzer and optional pump operating specifications when planning your system.
Applications
The LI-830 and LI-850 support a wide range of research, monitoring, and process-control applications:
Greenhouses, controlled environment agriculture, growth chambers, and grow rooms
