The HP478ACR is a robust combined probe for simultaneous measurement of relative humidity (%RH) and temperature (Pt100), built for use in demanding industrial and process environments. The stainless steel stem (Ø 14 mm, 130 mm length) provides mechanical durability, while the integrated stainless steel 20µ sintered filter effectively protects the sensing element against particulates and condensation. The SICRAM module enables direct plug-and-play compatibility with supported instruments, ensuring reliable signal quality and easy probe interchangeability. With a wide operating range of -40...+150 °C and 0...100 %RH, the probe is suited for a broad range of applications including process monitoring, storage environments, and industrial climate control. A 5 m connecting cable is included, offering extended reach for flexible installation in larger systems or hard-to-access measurement points.
