The CTC series is designed for both on-site and maintenance shop use. The applications are generally critical process control but can vary based on calibration and testing requirements. The user interface is easy and intuitive. One-key-one-function gives quick access to timesaving features such as the switch test or the auto-stepping function. The JOFRA CTC series consists of six different models that differ in temperature ranges and immersion depths. All models feature a large, backlit LCD display panel, which is easy-to-read even in well-lit areas. Units feature an informative display that provides icons and information regarding the status of the CTC and the calibration in progress.
The tall CTC models with an immersion depth of 190 mm / 7.5 in are ideal for calibration of liquid filled sensors. The specially designed non-linear heating elements in the CTC-650 B and the increased block mass provide a very homogeneous temperature throughout the block. It is essential for the quality of the calibration/test that the full lenght of the sensing part of the sensor is exposed to the same temperature. Calibrate analog reading devices or switches with very high repeatability.
The CTC-1200 A calibrator covers the temperature scale in the high range from 300 to 1205°C (572 to 2200°F) having an excellent stability of 0.1°C (0.18°F). The calibrator heats up very quickly and combining this ability with the standard auto stepping function makes it a very timesaving calibrator. Sensors tested by the CTC-1200 A are immersed 110 mm (4.3 in) into the insert to ensure that the whole thermo-sensitive part of the sensor is exposed to the required temperature.
