Senseca HP472ACR Temperature and Humidity Probe (SICRAM) | 0–100 %RH ±1.5 %RH, −20 to 80 °C, Pt100, for HD2101 / HD2301

Senseca HP472ACR Temperature and Humidity Probe: SICRAM Automatic Recognition

Overview

The HP472ACR is a Senseca (formerly Delta OHM) combined temperature and humidity probe with a capacitive humidity sensor plus Pt100 temperature sensor. Its built-in SICRAM module stores factory calibration data and is recognized automatically when connected to HD2101 and HD2301 instruments. The same series also includes the higher-temperature HP474ACR (−40 to 150 °C), HP475ACR (−40 to 180 °C), HP477DCR and others with different specifications, available on request.

Key Specifications
