EE872 incorporates the E+E dual wavelength NDIR CO2 sensor, which automatically compensates for ageing effects, is highly insensitive to pollution and ensures an outstanding long term stability. The multi-point CO2 and temperature adjustment leads to an outstanding measurement accuracy.
Due to its heated, replaceable sensing module, the EE872 is suitable even for high humidity and condensing environment. The IP65 enclosure and the PTFE filter cap offer excellent protection in polluted environment. With a catalytic filter cap, the EE872 is also appropriate for applications with periodical H2O2 sterilization.
The CO2 measured data is available on the analogue voltage or current output or on the RS485 interface with Modbus RTU protocol.
The free EE-PCS Product Configuration Software together with an optional adapter cable facilitates the configuration and adjustment of the EE872.
