Denmark-based AMETEX STC has introduced the JOFRA RTC-168 Reference Temperature Calibrator that is specific to sanitary sensors used in the food and pharmaceutical industries. This product provides a solution to the difficulty in calibrating such sanitary sensors due to their small sizes.

The RTC-168 features a new well design for sensors with large flanges, so they can easily get closer to the uniformity zone faster, and with improved accuracy. Its sensor basket has a temperature equalizer and faster magnetic stirrer. This extends the temperature uniform zone vertically for liquid calibrations, making it easier for smaller sensors to reach.

As an alternative to traditional bath method of calibration, the product incorporates a patent-pending technique that mimics the in-field use of the sensor. Liquid in the main block is isolated from the excess liquid around the flange, removing liquid flow effect, resulting in hassle-free calibration under different conditions. Liquid circulation is also optimised, and heat transfer is done through the heat conveyor’s aluminum, resulting in better consistency.

Further, the reverse flow cooling technique pushes hot air out of the bottom of the calibrator, providing a safer working environment for the technician doing the job. There is also a removable liquid container, with a screw-on lid and pressure relief valve that enables safe and clean transport of the calibrator.

“We have extensive experience with producing the highest quality temperature calibrators.  This knowledge helped us design the new RTC-168, which includes an industry-first innovation and other performance improvements,” said Haakon Harslund, Director of Engineering for AMETEK STC in Allerød, Denmark.

Haakon Harslund added, “We are very proud of our team’s ability to design and produce this innovative calibrator during such a difficult time.  Our team was able to continue to collaborate and creatively design while working from home.  The result is a calibrator that we know our customers will appreciate and that we are proud of.”
