Sensors with
Humidity Option
SCD Series
The all new SCD range of CO
2
transmitters with temperature sensing now combines
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.
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.
