CO2 Probe for OEM / HVAC Applications


The digital CO2 probe HLX871 covers a wide measuring range up to 10000ppm. The probe has a diameter of only 18.5 mm and a protection class of IP65. These features make the CO2 probe EE871 an ideal solution for handheld devices, data loggers or demanding HVAC applications.
The digital interface of the CO2 sensor allows for easy retrieval and processing of measurement values ​​and a unique configuration and adaptation to the application. Through the adjustable measuring interval, the average power consumption can be reduced to less than 60μA, which makes the CO2 probe HLX871 also the perfect solution for battery-powered devices.
The measuring principle of the CO2 probe HLX871 is based on infrared technology (NDIR). The patented auto-calibration does not require a regular supply of fresh air which makes the CO2 probe maintenance free. Aging effects are compensated by the auto-calibration easily. Against contamination the CO2 sensor is protected with a replaceable PTFE filter. Excellent long term stability is guaranteed.
The use in custom OEM solutions is the great strength of the CO2 probe HLX871. You simply ask your sales representative or send us your request. Our sensor specialists will advise you.
