The WR293 relative humidity sensor uses an integrated Hygrosmart sensor replaceable module with built-in replaceable sensors and cables. Because the instrument has remote probes of various sizes, it can be applied in high-temperature environments. Built in replaceable sensors facilitate re inspection and reduce maintenance costs. highlight Third output selectable Digital and Analog Signal Output Standards Replaceable probe Replaceable probe Temperature and humidity signals can be selected through software Metric and imperial units of measurement can be converted through software Can provide calculation of absolute humidity, dew point, frost point, and mixing ratio output
