The HX94 relative humidity/ temperature transmitter provides a reliable and low cost method for duct mount monitoring applications. Solid state sensors provide excellent sensitivity, fast response, and stability. Simple hookup and linearised output permit interfacing with most display and control devices. The NEMA 4 stainless steel enclosure and cable entry connection provides weather tight protection. The digital temperature and relative humidity sensor is protected by a stainless steel cap that is easily removed for cleaning.
