Series CDT-100-RLY Carbon Dioxide Transmitter
Series CDT-100-RLY, Carbon Dioxide Transmitter accurately monitors the CO2 concentration in indoor environments to help achieve energy savings. For increased sensor accuracy, a single beam dual wavelength non-dispersive infrared (NDIR) sensor is used to automatically correct the measurements.
Measurement range 2000 ppm (5000/10000 ppm) selectable by jumper. It gives analog and Relay output and supports various functions like recalibration function.
