     The MTC series of portable temperature calibrators from JF INSTRUMENTS makes it very easy to maintain correct readings for all your temperature monitoring devices. The dry-block design does not use any hazardous hot liquid, has a larger temperature range and heats up and cools down much faster than a traditional liquid bath. The MTC dry-block calibrators has been designed for much easier true temperature calibration in the field, leading to reliable results. The simple operation and the automatic functions have been carefully selected for ease of use. This has resulted in a fast, simple and efficient temperature calibrator without compromising quality. Reach 320°C (608°F) in just 4 minutes.

     The MTC series features a large backlit display showing a lot of useful information at the same time: The set value and the true temperature, the status on the thermo switch test input, a count- down time before the temperature is stable and a big check mark when it is stable. To save time use the automatic switch test. The MTC series will find the open and close temperatures on a thermo switch and calculate the dead band. The MTC series also features an auto-step function. Using this function you may stay in the control room and monitor the temperature reading while the calibrator automatically steps through a number of pre-programmed temperatures located next to the sensor.

Use of other inserts may reduce performance of the
calibrator. To get the best results out of the calibrator,
the insert dimensions, tolerance and material is critical.
We highly advise using JOFRA inserts, as they guarantee
trouble free operation.
