The CTC series is designed with an easy-to-read and very informative color display that gives you a full overview of the calibration task you are currently performing. The Jofra CTC-660 covers a wide temperature range from 28 to 660°C (82 to 1220°F).
Insert heat loss due to mass loading from multiple or large sensors can be a challenge for most dry-block calibrators. The CTCs advanced feedback algorithms combined with the external reference sensor effectively addresses these challenges and makes the accuracy even better.
The CTC is supplied with the highly versatile calibration software JofraCal. All calibrations can be documented with a certificate, given that the CTC is controlled from a PC. When the calibrator has reached the desired temperature and stability it will prompt you to type in the UUT temperature. JofraCal documents all your calibration needs within temperature, pressure and process calibration.
The CTC-660 is designed for both on-site and maintenance shop calibration with great portability in regard of size and weight. The calibrator is lightweight and easy to carry and with a handle placed away from the heat-zone.
