HK Instruments Brand CDT-MOD-2000 Duct CO2 transmitters

The CDT-MOD-2000 Duct series transmitters calibrate themselves automatically using ABC logic^TM. The ABC logic^TM requires that the space in which the transmitter is used needs to to be unoccupied for four hours per day so that the indoor CO₂concentration drops to the outside level. CDT-MOD-2000-DC Duct is a dual channel model with a measuring channel and a reference channel that makes a continuous comparison and the necessary adjustment accordingly. CDT-MOD-2000-DC Duct is also suitable for buildings that are continuously occupied. CDT-MOD-2000 Duct series devices include: • Separate Modbus output for each measurement parameter (CO₂ and T) • Mounting flange • Clear backlit display
