The WR285 relative humidity sensor uses a Hygrosmart sensor replaceable module, which can replace the probe and cable. Due to its remote transmission probe and various sizes, this instrument can be used in high-temperature environments. Built in replaceable sensors facilitate recalibration and reduce maintenance costs. highlight Maximum withstand pressure of 30 bar Digital and Analog Output Standards Replaceable probe The temperature and humidity output signals can be selected through software Metric and imperial units of measurement can be converted through software
