Ametek/ Jofra ATC Series Liquid & Dry Block Temperature Calibrator
Condition: Brand New
The unique active dual-zone heating block is designed to ensure optimum temperature homogeneity in the calibration zone of the block. This design eliminates the major uncertainties due to heat loss through the sensor-under-test and from the top of the block. The dry-block design combined with the external reference sensor input make the ATC series as accurate as a laboratory calibrator but maintain the speed and portability of a dry-block.
The ATC measures the output from the sensor-under-test directly: Thermocouples, RTD, mV, mA, and V. There is no need for multiple instruments. The JOFRA ATC series saves time by performing automatic stand-alone calibrations. Just run the downloaded work orders from the JOFRACAL calibration software. After completion of the work orders, the results may be downloaded into the computer for analysis, filing, and printing of certificates.

Liquid and odd/big size sensor calibration
Two models of the ATC series (ATC-140 and ATC-250) fitted with a 160 mm deep well with a diameter of 63.5 mm (2.5 in) can be used both as dry-block calibrators and as liquid calibration baths with a magnetic stirrer.
A liquid bath and a dry-block diameter of 63.5 mm (2.5 in), which is twice the size of any other JOFRA dry-block, are both new in the JOFRA product range. With these options it is now possible to calibrate even more temperature sensors at the same time and to calibrate large as well as odd sizes and shapes of sensors, which were not possible to calibrate in the existing range. The compromise compared to the existing models is longer cooling, heating and stabilization times.
ATC-140 & ATC-250 can be used without an external reference sensor, but if a STS-100 reference sensor is connected directly to a B version or the JOFRA reference thermometer DTI-1000, you obtain better accuracies and thereby use the full potential of the calibrators.
