Living Space CO
2
Sensors
with Humidity Option
SCR Series
The all new SCR range of CO
2
transmitters now combine the option of adding a
humidity transmitter into a single unit. Temperature sensing for all current platforms
is available dependent on the model selected thus offering lower cost installation.
Outputs are user selectable, 0 to 10V, 0 to 5V or 4 to 20mA.
The sensor is auto calibrating using the Auto Baseline Calibration (ABC) feature and
will sense CO
2
concentrations in the range 0 to 2000ppm with an accuracy of ±2% of
measured value (at 20deg C and 101.3kPa).
The transmitter also include a relay that will switch at 800/1000 or1200ppm
dependent on internal switch settings.
Replacement humidity tips are available including a 2% NIST certificated tip.
If calibration is required, order the standard product and the replacement 2% tip.
