CPC specs a wall-mounted infrared absolute dewpoint sensor with a 0-5VDC output for use in building control and anti-sweat control applications using CPC input boards.
Note that the HMW90 dewpoint probe model is shipped factory-configured. Do not adjust dip switch settings or configuration loss may occur to the unit. The model number can be identified by checking the label located on the side of the unit.
