E asy T emperature C alibrator

The JOFRA ETC400A heats up by up to 100°C / 212°F per minute and completes a full dual-point test in less than 10 minutes, including stability time; timesavings at your fingertips!  The JOFRA ETC series is designed for field testing of temperature measurement devices.  The small size and light weight make it a perfect instrument to verify sensors in difficult to reach places.  All JOFRA ETC units have many of the same useful and timesaving features as the more advanced JOFRA dry-block series. 

Model and temperature range 
ETC125A..........-10 to 125°C / 14 to 257°F 
ETC400A..........28 to 400°C / 28 to 752°F

Key features: All units with dual-zone heating block New super-cooling model (ATC-157) Universal input for sensor-under-test Input for external reference probe Automatic switch test RS 232 and AmeCal calibration software Multi information display + numeric keyboard Autostepping Stability indicator Count-down timer (shows when unit is stable) Automatic, stand-alone calibration system Up- and download of work orders (calibrations) MVI Mains Variance Immunity

A dvanced T emperature C alibrator

The JOFRA ATC series combines the accuracy of a laboratory calibrator with the speed and portability of a dry-block calibrator.  The series features the new dual-zone heating / cooling block to ensure the thermal performance in the calibration zone independent of the load. 

Model and temperature range 
ATC-156..........-24 to 155°C (-11 to 311°F) <-- New dual-zone cooler 
ATC-157..........-45 to 155°C (-49 to 311°F) <-- New dual-zone super-cooler
ATC-320..........33 to 320°C (122 to 1202°F) 
ATC-650..........33 to 650°C (122 to 1202°F)
