■ Multi-Information Display Status Bar - Shows information about recalibration due status, hot and cold safety warnings, and date and time. Calibration Settings - Shows the calibration settings and stability criteria for the reference sensor. Can be accessed and changed directly in the display by use of the arrow keys. Calibration Status Shows current status of the calibrator, like heating or cooling, expected time to stability, or stability achieved. Shows the current possibilities of the function keys. The function keys serve as shortcuts to the main functions like Set, Preset, Auto step, and...

Useful Features The CTC is a very versatile calibrator series with many integrated functions - you can run the calibration in four different ways. Preset Mode MVI – Mains Power Variance Immunity improves temperature stability Unstable mains power supplies are a major contributor to calibration inaccuracies. Traditional temperature calibrators often become unstable in industrial environments where large electrical motors, heating elements, and other devices are periodically cycled on and off. The cycling of supply power can cause lower quality temperature regulators to perform inconsistently,...

I Special Features Multi Sensor Calibration Insert heat loss due to mass loading from multiple or large sensors can be a challenge for most dry-block calibrators. The CTCs advanced feedback algorithms combined with the external reference sensor effectively addresses these challenges and makes the accuracy even better. When switching on the calibrator or connecting the reference sensor, the calibrator immediately warns you if any of the calibration certificates are overdue. A buzzer and warning appears. The recalibration interval can be set from 1 to 99 months. All STS reference sensors are plug...

User Specified Settings Calibration Software Included The CTC is supplied with our highly versatile calibration software JofraCal. All calibrations can be documented with a Silent Mode Operation The CTC calibrator can be programmed to run in silent operation. This function is an advantage if calibrating in a laboratory or an office. If used in silent operation the calibrator is not using its full cooling potential. Online Firmware Upgrade certificate, given that the CTC is controlled from a You can download firmware and software upgrades at type in the UUT temperature.
