B and C models only » Display indicator Shows the degree of temperature uniformity in the insert when using the new DLC technology. B and C models only » 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 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-156/157 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 manufacturers of temperature dry-block calibrators. We are proud to introduce our top model RTC (Reference Temperature Calibrator), which is no exception to the above and 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 design • New multi-hole insert kits covering all the most used sensor sizes • High profile design and the well-known long lasting JOFRA quality The new RTC calibrator comes in three different models – A, B, and C. • RTC-A reference temperature calibrator • RTC-B reference temperature calibrator with input for reference sensor, DLC sensor and sensors-under-test • RTC-C reference temperature calibrator with input for reference sensor and DLC sensor

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 JOFRA RTC-series features our well-known active dualzone 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...

New multi-hole insert kits Two special multi-hole insert kits have been developed to comply with calibration of almost any sensor diameter without having to buy numerous inserts. Intelligent reference sensors The JOFRA STS-200 intelligent reference sensors as well as the new DLC sensor are all containing all individual calibration data regarding the sensor. The first kit is a metric insert kit consisting of only four inserts covering all diameters from 3 to 13mm. The other is an imperial insert kit consisting of only three inserts covering six different sizes from ⅛” to ½”. All inserts have holes...

Special designed carrying case SET-Follows-TRUE (model B & C only) AMETEK has designed an all-in-one-handle carrying case. Available on B and C models only, the “SET-Follows-TRUE” makes the instrument tune in until the temperature reading of the external reference “TRUE” meets the desired “SET” temperature. This feature is important when it is critical that the temperature of the calibration zone matches the desired temperature when measured with accurate external reference sensors. We have now made it possible to store both the STS reference sensors and DLC sensors in the carrying case with...

Enhanced stability JOFRACAL calibration software A stability indicator shows when the RTC calibrator has reached the desired temperature and is stable. The user may change the stability criteria for the external reference and the sensor-under-test quickly and simply. The stability criterion is the user’s security of a correct calibration. A count-down timer is displayed next to the temperature read-out. JOFRACAL is a highly versatile calibration software that is supplied together with the RTC calibrators. The software ensures easy calibration of all kind of temperature sensors, such as RTD´s,...
