The AMETEK 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.

CTC-320 and CTC-650 are exceptionally fast and have deep immersion depths of 200 mm (7.9 in). The CTC-320 A heats up to maximum temperature in just 4 minutes and the CTC-650 A in just 10 minutes. The fast performance of the heating block is due to a special profile that minimizes the mass, but still contains a 26 mm (1 in) insertion tube. The design is a balanced compromise between temperature stability / homogeneity and fast heating / cooling.

The CTC-320 B and CTC-650 B models offer a deeper immersion depth of 200 mm / 7.9 in. If you have liquid-filled sensors or other sensors that require a deeper immersion depth, look for the B versions. While the units do not heat and cool as quickly as their shorter counterparts, they offer the capability to accommodate longer sensors.

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.
