Introduction
The Endress+Hauser iTHERM TrustSens TM372 is the imperial-style version of the world’s first fully self-calibrating RTD thermometer, purpose-built for hygienic and aseptic processes in food, beverage, and life sciences industries. Featuring automated in-situ calibration at 118 °C (SIP) and 39 °C (CIP), paired with Heartbeat Technology, it eliminates production downtime for recalibration while maintaining continuous compliance with FDA, 3-A, and EHEDG standards.
