The Intempco HTX series humidity / temperature transmitters are designed for use in HVAC energy management.
The HTX01-C01 is an interior wall mount RH transmitter. The small off-white plastic enclosure is esthetic and takes up very little space. They are designed for mounting directly to walls or any flat surface.
The HTX02-C01 is a high performance low cost Interior/Exterior DUCT mount RH transmitter. The enclosure is Polycarbonate NEMA 4X and the probe is PVC with an HDPE porous filter.
They are designed for mounting directly into ventilation DUCTs.
The HTX03-C01 is a high performance low cost Interior/Exterior RH transmitter. The enclosure is Polycarbonate NEMA 4X and the probe is PVC with a HDPE porous filter.
They are designed for mounting directly on walls or support brackets inside or outside. Outside mounting requires protection form the elements.
