Accurate and Long-Term Stable

With its temperature range -40...60 °C (-40…140 °F), the EE872 is appropriate for most CO₂ monitoring applications. The multi-point CO₂ and temperature adjustment ensures best accuracy over the entire working range. The probe incorporates the E+E dual-wavelength NDIR CO₂ sensor, which is highly insensitive to pollution. Due to auto-calibration, the sensor also shows excellent long-term stability.

Pressure and Temperature Compensation

On-board sensors compensate the effect of temperature, altitude or weather changes on the CO₂ measurement. This leads to highly accurate CO₂ reading independently of the environmental conditions.

Heated, Interchangeable CO₂ Sensing Module

The heating prevents condensation inside the sensing head. Thus, the EE872 is appropriate for use in in high humidity and condensing environment. The modular design facilitates the replacement of the interchangeable, pluggable sensing module.

Robust and Well Protected

The robust IP65 stainless steel or plastic enclosure and the replaceable PTFE filter cap provide optimum protection against contamination. With a special catalytic filter, the CO₂ probe is suitable for applications with periodic H2O2 sterilization.

Analogue or Digital

The EE872 provides the CO₂ measured data simultaneously on current and voltage outputs or via RS485 interface with Modbus RTU protocol.

Configuration and adjustment can be performed comfortably with the free configuration software and an optional adapter cable.
