The Ametek Jofra CTC Series 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. With the use of the optional external reference probe, this is the most accurate industrial class temperature calibrator on the market. CTC Series is available in three versions. The CTC-155 covers a temperature range of -25° to 155°C (-13° to 311°F).

Tariff fees or manufacture imposed surcharges may be applicable.
