Key Features:

  • High accuracy Down to ±0.04°C using the external reference sensor. 4-wire True-Ohm-Measurement technology is used
  • Excellent stability 0.01˚C
  • Wide temperature range
    RTC-158 from -22 to 155°C (-8 to 311°F)
    RTC-250 from 28 to 250°C (82 to 482°F)
  • Excellent temperature homogeneity Unique active dual-zone block ensures good temperature homogeneity in the calibration zone
  • DLC Dynamic Load Compensation Perfect temperature uniformity in the insert, even when calibrating large sensors or many sensors at a time. B and C models only
  • Temperature uniformity indicator Shows the degree of temperature uniformity in the insert when using the new DLC technology. B and C models only
  • New sensor basket In combination with the stirrer the newly developed sensor basket ensures virtually zero axial and radial gradients in the calibration zone
  • Intelligent reference sensors JOFRA reference sensors are supplied with intelligent plugs, holding the calibration data (coefficients) of the reference sensor. This is
    a truly plug’n’play calibration system
  • USB communication All RTC calibrators communicate via an easy-to-use USB port
  • EURAMET Best performing dry-block with regard to the EURAMET/cg-13/v.01 guideline for testing of dry-blocks

Ametek JOFRA RTC-250: High accuracy, excellent stability 0.01C, wide temperature range. Range: 28 to 250°C

Advantages of the combined liquid bath/dry-block calibrator

  • • Automatic calibration of as many as 24 sensors at a time
  • • For customers, who only want to use liquid baths
  • • For calibration of odd sizes and shapes of sensors including sanitary sensors

            WET = no need for inserts, that fit the sensors
            DRY = more space for calibration of special sensors

  • • Industries who need to calibrate many sensors at a time or short sensors can benefit from the big well
  • • JOFRACAL software and RTC B-models can handle on-line calibration and documentation of multiple sensors calibrated simultaneously

Use of other inserts may reduce performance of the calibrator.
To get the best results out of the calibrator, the
insert dimensions, tolerance and material is critical. We
highly advise using JOFRA inserts, as they guarantee
trouble free operation.
