CTC Series - Compact Temperature Calibrator

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 CTC Series also utilises MVI circuitry that has been adopted from the original ATC series, which ensures stable temperatures even when the mains supply is unstable.

The CTC series consists of nine 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 six new CTC models released in May 2016 feature significant improvements over the existing, highly successful CTC series. These include higher accuracy, a broader temperature range, added functionality/automation and the option of a reference temperature input with the C models. 

The new CTC Models also have a new, crisp, color display with improved navigation similar to the RTC models.
