E E ELEKTRONIK EE820 CO Sensor for Demanding User Guide
The EE820 CO2 sensor is optimized for use in harsh, demanding applications, such as hatchers, incubators, life stock barns or greenhouses.
Outstanding Accuracy
A multiple point CO2 and temperature factory adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range, so the EE820 can even be installed outdoors.
Long-term Stability
The EE820 incorporates the E+E dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability.
High Resistance to Pollution
With its robust, functional IP54 enclosure with a special filter the EE820 can be employed even in harsh environment.
Fast Response Time
The fast response time version of EE820 is fitted with a forced air circulation module installed behind the filter.
Analogue and Digital Outputs
The CO2 measured data range up to 10 000 ppm is available on the analogue output (voltage / current) or on the RS485 interface with Modbus RTU or BACnet MS/TP protocol.
Easy Configuration and Adjustment
An optional adapter and the free EE-PCS Product Configuration Software facilitate the configuration and adjustment of the EE820.
