JOFRA ATC-125 - the coolest temperature calibrator in the world

The JOFRA ATC-125 ultra cooler features a unique free piston stirling cooler technology for optimum performance and superior temperature homogeneity throughout the block at very low temperatures. The JOFRA ATC-125 ultra cooler is the world’s first temperature dry-block calibrator capable of reaching -90˚C. Featuring patent-applied for Free Piston Stirring Cooler (FPSC) technology for cooling, together with a special heating element, the ATC-125 offers high accuracy, excellent stability and extremely fast heating and cooling times.

The ATC-125 ultra cooler calibrator may be used to perform fully automatic calibration routines without using an external computer. It is also possible to use the computer for full upload and download capabilities. The ATC-125 may also be supplied with inputs for external reference sensors and for sensors-under-test. All ATC calibrators feature RS232 serial communication and the standard delivery also includes the JOFRACAL calibration PC software.
