RTC Series Temperature Calibrators

The RTC Series are some of the most advanced and accurate temperature calibrators on the market, and the series of calibrators with the widest temperature range available.

A unique feature to the RTC Series temperature calibrators is the patented DLC (Dynamic Load Compensation) system that ensures perfect temperature uniformity in the insert, even when calibrating large sensors or multiple sensors at a time.

An active dual and triple zone temperature control provides excellent temperature homogeneity in the well.

The large color display is easy-to-read and provides icons and information regarding the status of the calibrator and the calibration in process. Popular functions like automatic switch test and auto stepping are available with special one-key-one-function buttons.

  • Temperature range from -100 to 700°C (-148 to 1292°F) with 7 models
