LI-830 CO2 and LI-850 CO2/H2O Analysers for Continuous Measurements
For Continuous Monitoring Applications
High-performance monitoring solutions that give accurate, stable readings. Easy-to-use software and minimal maintenance provide hassle-free measurements for a wide range of applications and system integration options.
Flexible configurations and outputs for a variety of applications.
Easy Operation

Just plug it in and you’re ready to go
With the new optional pump and display, just power the instrument on, and measurements appear immediately. View real-time measurements, configure graphs, or set up logging options with the easy-to-use software.

Keep it simple with minimal maintenance
Ensure continuous operation and minimize downtime with a user-cleanable optical bench, and no need for factory recalibration.

Easily view or log measurements
Windows® and Mac® interface software display real-time concentrations and graphs. Easily set up operational parameters and logging options, and view analyzer diagnostics.
Growth Chambers and Greenhouses
Analyzers can be configured to monitor CO2/H2O and trigger fans or injection of CO2 and/or H2O, keeping levels within a desired range. User-supplied relays can also trigger devices such as pumps, valves, dialers, or audible alarms.


Atmospheric Monitoring
Analyzers have the stability and durability to continuously monitor atmospheric CO2 and H2O. The included software facilitates configuration, control, data collection, and graphical data display.
Other common applications include:
- Measuring pCO2 and DIC
- Indoor air quality monitoring
- Building system efficiency (ventilation systems)
- Process control
- Bioremediation
- Atmospheric profiling
- Leakage monitoring
- TOC analysis systems
- Volcanology
