Temperature range: -100° to 700°C  Have a look at our RTC video!

With DLC system for perfect temperature homogeneity in the insert - even when calibrating large sensors or many sensors at a time.

AMETEK continues to develop new techniques to improve the performance, accuracy, convenience and functionality of the widely known JOFRA calibrators. By this, we strengthen our position as a leading manufacturer of temperature calibrators.

We are proud to introduce our top line RTC series. These models are more demanding and sophisticated than any existing calibrators.

The new RTC calibrators are available in three versions - A, B, and C. 

1. A "Reference Temperature Calibrator"
2. B "Reference Temperature Calibrator" with inputs for the reference sensor, the sensor and the DLC specimens
3. C "Reference Temperature Calibrator" with inputs for the reference sensor and DLC sensor  

Properties of the RTC series  High accuracy

Up to ± 0.04°C (RTC 700: up to ± 0.11°C) with use of the external reference sensor.   Excellent stability: ± 0.005°C (RTC-700: up to ± 0.008°C)   Wide temperature range RTC-156: -30 to 155°C RTC-157: -45 to 155°C RTC-158: -22 to 155°C, Bath Dry-block/Liquid RTC-159: -100 to 155°C ultra-cooler RTC-250: 28 to 250°C, Bath Dry-block/Liquid RTC-700: 33 to 700°C


Improved temperature homogeneity
The unique active dual-zone block ensures good temperature homogeneity in the calibration zone safely.

  DLC - Dynamic Load Compensation               PATENT PENDING!
Perfect temperature homogeneity in the insert, even when the calibration of large sensors or more sensors at the same time. Only present on the B and C models.   In the display for the temperature homogeneity Shows the temperature in °C in the homogeneity of the insert when the DLC technology is used.

Only present on the B and C models.


Intelligent reference sensors
JOFRA reference sensors are supplied with intelligent plugs, which are located in the calibration data (coefficients). This is a true "plug and play" system. The data of Referenssensors müsssen not be entered manually.

USB communication
All RTC calibrators have a USB interface.

Time-saving
Very fast cooling and heating times.

EURAMET
Best dry block overlooking the EURAMET/cg-13v.01 Directive for testing dry blocks.
