JOFRA MTC Series - Marine Temperature Calibrator

Fast and convenient marine temperature calibrators

MTC - Marine Temperature Calibrator

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.

MVI - Mains Variance Immunity MVI - Mains Variance Immunity Temperature dry-block calibrators from AMETEK employ the MVI, thus avoiding such stability problems. The MVI circuitry continuously monitors the supply voltage and ensures a constant energy flow to the heating elements. JOFRACAL calibration software JOFRACAL calibration software ensures easy calibration of RTD´s, thermocouples, transmitters, thermoswithes, pressure gauges and pressure switches.
