Ametek Jofra CTC-660 Dry Block Calibrator, 28 to 660 °C, compact calibrator
Ametek Jofra CTC-660 Dry Block Calibrator
Overview
The CTC series is Jofra's industrial compact temperature calibrator, built for on-site and maintenance-shop calibration. The CTC-660 spans 28 to 660 °C with an accuracy of ±0.85 °C using the internal reference sensor, improving to ±0.45 °C when the optional external STS-120-A-966 reference sensor is fitted. MVI mains power variance immunity keeps the block stable even when supply voltage fluctuates in industrial environments.
Fast calibration is the priority: heating from 23 to 660 °C takes 18 minutes, time to stability is about 5 minutes, and set, preset, auto-step and switch test functions handle quick routines. The informative color display, USB 2.0 interface with JofraCal calibration software, interchangeable inserts and the heat shield supplied as standard round out the package for workshop duties.
