Save Time, Save Money Best In Class Industrial Calibrator Fast Calibration The new generation CTC temperature calibrators All Jofra temperature calibrators feature a feature improved accuracy by as much as 25%. They purpose-dedicated temperature regulator, are now the most accurate industrial class tempera- which provides a very fast heating and cooling ture calibrator on the market. time, and a short stabilization time. Performing a three point temperature calibration procedure is fast and easy. Wide Temperature Range The CTC series covers a wide temperature range The CTC series is designed...

External Reference Sensor Self Calibration Each CTC calibrator has a C model that includes a signal input for an external reference sensor. The sensor improves the accuracy even more. Our external reference sensors have been developed to match each of the CTC models. Adjust the internal reference sensor to give the same readings as the external reference sensor by performing a Self Calibration. After the Self Calibration the calibrator can be used without the external reference sensor. Regular Self Calibration is needed to ensure the accuracy. The Self Calibration is simple and fast to perform...

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. 30.00 Preset | Auto step | Switch Function Keys Informative Color Display and Intuitive Operation The CTC series is designed with an easy-to-read and very informative color display that...

■ Useful Features MVI - Mains Power Variance The CTC is a very versatile calibrator series with many integrated functions - you can run the calibration in four different ways. , ... Immunity improves temperature Set Function Preset Mode stability Unstable mains power supplies are a ma- jor 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...

Multi Sensor Calibration Plug and Play Reference Sensors 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. All STS reference sensors are plug and play as they contain information in the connectors memory chip: Sensor coefficients • Unique serial number • Temperature range • Calibration date • Calibration interval Broad Range of Inserts IRI - Intelligent Recalibration Information...

■ User Specified Settings Calibration Software Included 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 Support Rod Set The support rod can be mounted on all CTC calibrators, and it is used to hold the sensor under test in its position while calibrating. Indcludes rod, sensor grip, and fixture. The CTC is supplied with our highly versatile calibration software JofraCal. All...
