The award-winning iTHERM TM371 smart thermometer integrates a HART® transmitter and Heartbeat Technology and is equipped with the world's first fully automatic in-situ self-calibrating RTD sensor. It effectively prevents the risk of undetected non-compliance in food & beverage and life sciences industry applications, shortens production downtime and increases product safety and process efficiency. The product fully complies with FDA 21 CFR Part 11 and GMP standards.
Advantages
The self-calibration function and “Heartbeat Technology” reduce operating risk and costs
Thanks to the fully automatic and fully traceable built-in self-calibration function, the production process does not need to be interrupted
Fully automatic archiving of records, with storage of 350 calibration points.
Calibration certificates can be printed for use as audit documentation.
Automatic 4-20 mA loop testing saves time and increases process safety. Learn how iTHERM TrustSens performs fully automatic loop testing in five simple steps. The video shows the device setup and how your process benefits.
Avoids non-compliance or undetectable faults
