The HP475ACR and HP475AC1R are robust combined probes for simultaneous measurement of relative humidity (%RH) and temperature (Pt100), designed for demanding industrial and agricultural applications. Both probes feature a stainless steel stem and integrate a SICRAM module for plug-and-play compatibility with supported instruments. The HP475ACR covers an operating range of -40...+150 °C and 0...100 %RH, with a pointed tip (Ø 14 x 75 mm) optimized for penetration measurements — including water activity monitoring in grains. The HP475AC1R extends the temperature range to -40...+180 °C and adds a stainless steel 20µ sintered filter for enhanced protection of the sensing element in contaminated or humid environments. Both models include a 2 m connecting cable and are built for reliable long-term use in process, environmental, and storage monitoring.
