RTC Reference Temperature Calibrator

RTC Series Temperature Calibrator
Our most advanced and accurate portable temperature calibrator with the widest available temperature range. One of its great features is the patented DLC system for perfect temperature uniformity in the insert – even when calibrating large sensors or many sensors at a time. 

The RTC Series also feature active dual- and triple-zone temperature control which provides excellent temperature homogeneity in the well.

Our latest calibrator is our most advanced yet.  Our new RTC-168 Combination Dry-Block / Wet Bath Temperature Calibrator provides the advantage of both in a portable package.  In addition to its versatility, it also includes innovative patent-pending features designed to calibrate difficult sanitary sensors.  Some of the key features include:

• New Liquid System with a faster magnetic stirrer to extend the uniformity zone
• More space to support large flange sensors up to 84 mm in diameter
• A removable liquid container making switching from dry to wet clean and easy
• Screw on lids for quick portability
• Special sanitary sensor insert for dry block mode
• Unique airflow system to protect sensors-under-test
• New IP68 reference sensor compatible with dry and wet modes

Every RTC model includes our advanced simplicity user interface, which is available in English, German, Chinese, and Japanese.

• Temperature range from -100 to 700°C (-148 to 1292°F) with 7 models
• Accuracy to ± 0.04°C and Stability to ± 0.005°C
• Dry block and liquid bath / dry block combined
• Time saving fast cooling and heating times
• Contamination free calibration of clamp sensors
• “Plug and Play” intelligent reference sensors
• Easy-to-read color display with User-friendly navigation
• Lightweight and easy to carry
• Multi-hole insert kits
• JofraCal Calibration Software
• Inputs for Thermocouple Calibration
