CTC Series 

The CTC Series portable temperature calibrator is a fast, time-saving, reliable dry block temperature calibrator designed for on-site use. The large colour 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.

• Temperature range from -25 to 1205°C (-13 to 2201°F) with 5 models
• Accuracy to ± 0.2°C and Stability to ± 0.04°C
• Calibrate Long Sensors with the CTC-652s 190 mm immersion depth
• Lightweight and easy to carry
• Multi-hole and/or insert kits
• Input for external reference sensor on all C models
• MVI circuitry ensures stability despite mains supply variations
• Rugged, portable temperature calibrator
