EE820
The EE820 CO
2
sensor is optimized for use in harsh, demanding
applications, such as hatchers, incubators, life stock barns or
greenhouses.
Outstanding Accuracy
A multiple point CO
2
and temperature factory adjustment
procedure leads to excellent CO
2
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 CO
2
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 lter the
EE820 can be employed even in harsh environment.
Fast Response Time
The fast response time version of EE820 is tted with a forced air
circulation module installed behind the lter.
Analogue and Digital Outputs
The CO
2
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 Conguration and Adjustment
An optional adapter and the free EE-PCS Product Conguration Software facilitate the conguration and adjustment of
the EE820.
