Rotronic CF8-W-DISP-GH CO2 carbon dioxide measurementinstrument is used to measure the quality of air and levels of CO2, particularly in greenhouses.
The indoor air quality (IAQ) sensor is used to measure indoor air carbon dioxide concentration and air temperature within greenhouses.
The Rotronic CF8-W-DISP-GH gas measurement transmitter features self diagnostic procedures and a full system test is carried out every time the device is turned on.
In addition, throughout operation the sensor probes are checked against failure by checking the valid dynamic measurement ranges.
ROTRONIC CF8-W-DISP-GH CO2 GAS MEASUREMENT TRANSMITTER WITH RELAY FOR USE IN GREENHOUSES
The Rotronic CF8-W-DISP-GH CO2 gas measurement transmitter is virtually maintenance free and an internal self adjusting calibration function takes care of the normal long term drift associated with the CO2 sensor.
In order to secure the highest level of accuracy, a time interval of five years is recommended between CO2 calibrations unless a special situation has occurred. A zero calibration can be performed by the use of pure nitrogen or air that has passed through a chemical absorber.
