John Morris Scientific has introduced LI-Cor's single path, dual wavelength, non-dispersive infrared, CO2 gas analyser, the LI-820.
The LI-820 is used for continuous monitoring of CO2 in a range of environmental conditions including ocean science, plant science, geological monitoring and greenhouse control systems.
The CO2 measurement is a function of the absorption of infrared energy as it travels through the optical path.
The optical path is a thermostatically controlled infrared detection system, which is claimed to provide excellent stability over time and temperature, extending the required interval between calibrations.
User-defined high and low-level alarms are available as voltage outputs, allowing the user to control CO2 within a desired range.
Relays can trigger devices such as automatic diallers, alarms, pumps and valves in industrial environments.
The LI-820 includes Windows interface software for user calibration and data collection.
Users can set operational parameters and logging options, as well as output data to a printable chart.
