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
- Accuracy to ± 0.04°C and Stability to ± 0.005°C
- Dry-block and dry-block/liquid bath combinations available
- Lightweight and easy to carry
- Multi-hole insert kits
- Inputs for thermocouple calibration
- MVI circuitry ensures stability despite mains supply variations
- Rugged, portable temperature calibrator
JOFRA offers 7 different models of the RTC temperature calibrator. For more information about each model click on the datasheet below.
