The digital EE871 probe from E+E Elektronik measures CO2 concentration up to 50,000 ppm (5 % CO2). The compact probe is now available with a special filter cap, which ensures high accuracy and long-term stability in H2O2 contaminated environment. This opens up new applications for the EE871, particularly in the pharmaceutical and biotech industries, where hydrogen peroxide is used for cleaning and sterilization purposes.
CO2 infrared measuring principle
The CO2 infrared measuring principle (NDIR dual-wavelength technology) of the EE871 is inherently insensitive to contamination. The auto-calibration compensates for ageing effects and provides excellent long-term stability. Thanks to the multi-point CO2 and temperature adjustment, the EE871 offers a high measuring accuracy over the entire temperature range from -40 °C to 60 °C (-40...140 °F).
Configuration and adjustment
The measured values are optionally available on the Modbus RTU interface (up to 10,000 ppm) or the E2 interface (up to 50,000 ppm). Configuration and adjustment of the probe can be performed comfortably with the optional adapter kit.
