Reference Temperature Calibrator 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 » Excellent temperature homogeneity id bath for liqu use Both -block nd dry a Unique active dual-zone block ensures good temperature homogeneity in the calibration zone Patent Dynamic Load Compensation g! Perfect temperature uniformity in the pendin Liquid Bath 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 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 AMETEK continues to develop new techniques to improve performance, accuracy, convenience and functionality of the well-known JOFRA calibration products. By doing so, we maintain our position as the leading worldwide manufacturer of temperature dry-block calibrators. Advantages of the combined liquid bath/dry-block calibrator Calibration of many sensors at a time due to more space for example in connection with validation of many thermocouples, which saves time • 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 All RTC calibrators communicate via an easy-to-use USB port Best performing dry-block with regard to the EURAMET/cg-13/v.01 guideline for testing of dry-blocks ISO 9001 Manufacturer Specification Sheet, SS-RTC-158/250

We are proud to introduce our new top model RTC (Reference Temperature Calibrator) series, which is even more sophisticated than any existing calibrators. The RTC offers many new fantastic features, such as: • Patent pending DLC, Dynamic Load Compensation system, for perfect temperature uniformity in the insert • Unique intelligent sensors for plug’n’play connection • USB connector for communication • Easy-to-read color VGA display with perfect overview of the actual status • Intuitive, fast and user-friendly navigation • Lightweight and easy to carry around • New functional carrying case...

These inserts have holes for both the DLC and two reference sensors (4 mm and 1/4”). These holes are marked for correct use. Intelligent reference sensors With this multi-hole insert in the carrying case the user is able to calibrate all the most commonly known sensor sizes. The JOFRA STS-200 intelligent reference sensor as well as the new DLC sensor are both containing all individual calibration data regarding the sensor. Firstly, this means that the time-consuming coefficient downloading sequence with risk of errors is no longer necessary. Secondly, the user can change the reference...

The new integrated support rod is part of the reduced weight philosophy. It is lightweight and very easy to mount on the RTC. Two fixing holes are integrated in the calibrator where the support rods can be mounted. The support rod is especially useful in bath calibration. Special designed carrying case AMETEK has designed an all-in-one carrying case. We have now made it possible to store both the STS reference sensors and the DLC sensor in the carrying case with an optimum physical protection. There is room for inserts, insulation plugs and calibration oil as well as compartments for the...

Instrument setups The RTC series allows the user to store up to ten (10) complete instrument setups. You may store all sorts of information including temperature units, stability criteria, use of external reference sensors, resolutions, sensors-under-test (SUT), conversions to temperature, display contrasts, etc. The setup may be recalled at any time. Maximum and minimum temperature From the setup menu, the user can select the maximum and minimum temperature limit for the calibrator. This function prevents damage to the sensor-under-test caused by excessive temperatures and it helps...

Unique temperature performance The RTC series of calibrators provides precision temperature calibration of sensors, whatever the type or format. This is accomplished through an innovative active dualzone heating technology. The RTC-series features our well-known active dual-zone heating technology. Each heating zone is independently controlled for precision temperature calibration. The homogeneity in the lower part is close to that of a laboratory liquid bath. The lower zone ensures optimum heat dissipation throughout the entire calibration zone. The upper zone compensates for heat loss...
