CARBOmet series CO2 analysers use a cell based on non-dispersive infrared technology.
The basic functions meet every type of application requirement and include:
– Microprocessor control
– Analysis display on a 4-digit LED display
– 2 fully user-configurable set-points with relay output
– Audible alarm
– Linear 4…20 mA output
– RS 232 serial output (standard) or RS 485 (optional), ModBus RTU protocol
– Programming using three buttons on the front panel
– Adjustable Zero and Span calibration using dedicated commands in the device menu.

Applications
Process monitoring for air analysis control in greenhouses
Process monitoring for air analysis control in hyperbaric chambers
Air monitoring in modified atmospheres for food packaging
Process monitoring in industry and laboratories
