The Ametek CTC series is a fast dry-block that offers both interchangeable inserts, the MVI stability circuitry, and calibration software. Both speed and portability are superior to liquid baths. Dry-block calibrators do not require hazardous liquids and provide a wide temperature range. Calibrate RTD's, thermocouples, thermoswitches, thermistors, and other common temperature sensing devices.

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 you quick access to timesaving features such as the switch test or the auto-stepping function.

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 JOFRA CTC series consists of six different models that differ in temperature ranges and immersion depths. All units offer similar features. A rugged, slim-line, aluminum outer casing with die-cast top and bottom protects the CTC series of dry-block calibrators. For easy documentation and automatic calibration, all units are delivered with RS232 serial communication and JOFRACAL calibration software.

The CTC-320 A and the CTC-650 A contain an innovative heating block profile. This design heats up the CTC-320 A to maximum temperature in just 4 minutes and the CTC-650 A in only 10 minutes. The fast performance of the heating block is due to the special profile that minimizes mass and yet, still accepts an insertion tube with a 25mm / 1 in. outer diameter. This design is a balanced compromise between temperature stability / homogeneity and rapid 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 accomodate longer sensors.
