The CTC Series provides portability and ease-of-use at a reasonable cost, without sacrificing accuracy, performance, or features. The CTC Series also features dual zone temperature control which provides excellent temperature homogeneity in the well.
CTC-155 -25 to 155°C / -13 to 311°F
CTC-320 28 to 350°C / 82 to 662°F
CTC-650 28 to 660°C / 82 to 1220°F
The new generation of the CTC temperature calibrator has improved the accuracy with as much as 25%. This makes it the most accurate industrial class temperature calibrator on the market.
The CTC series covers a wide temperature range from -25 to 660°C (-13 to 1220°F). This makes itsufficent to cover almost all standard industrial temperature calibration applications.
All our Jofra temperature calibrators feature a purpose-dedicated temperature regulator. This provides a very fast heating and cooling time as well as a short stabilization time. Performing a three point temperature calibration procedure is fast and saves time.
All our C Models are designed with a signal input for an external reference sensor. The sensor makes it possible to improve accuracy even more. Our new range of external reference sensors have been developed to match each of the new CTC’s.
The CTC can be run in two modes when using the external reference sensor. “External ref” mode is where the external reference sensor represents the True value. The “Set follows True” mode is where the reference sensor serves two purposes;measuring the reference temperatue and at the same time controlling the block temperature to the set temperature.
The CTC series is designed for both on-site and maintenance shop calibration. We have focused on 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.
The CTC Series portable temperature calibrator is a fast, time-saving, reliable dry block temperature calibrator designed for on-site use. The large color display is easy-to-read and provides icons and information regarding the status of the calibrator and the calibration in process. Popular functions like automatic switch test and auto stepping are available with special one-key-one-function buttons.
Speed, portability, cleanliness, and wide temperature range are all superior over liquid bath systems.
