Easy-to-use and equipped with a large graphical display, TC temperature calibrators are the perfect field tools for easy and quick maintenance and commissioning of temperature transmitters and probes.

TC 6621 temperature calibrator measures or generates thermocouple temperatures (16 different types) and voltage at an accuracy of 0.02%.

TC 6622 temperature calibrator measures or generates RTD temperatures (12 different types) and resistance at an accuracy of 0.02%.

With a very low temperature coefficient (10 ppm/°C in thermocouples and 7ppm/°C in resistance), IP54 protection and robust design, TC calibrators are suitable for onsite use even in demanding environmental conditions. They are widely used in the energy field, engineering sector, metal industry and automotive field.

TC calibrators use a graphical interface making programming and reading easier, under graphical or test format. Due to memory feature (10,000 values) and extended functionalities (square root, steps, synthesizer, statistical functions…), TC are well adapted to different process job procedures and ensure full data traceability as well as advanced data exploitation. Use them together with DATACAL calibration software to display, manage data and issue your own customized calibration certificates.

TC calibrators are delivered with 4 alkaline AA batteries in standard. The optional battery charger used a rechargeable battery.

Key features:

  • High accuracy: 0.02% reading with an adjustable resolution of 1 µV (TC 6621) and 1 mΩ (TC 6622)
  • Values displayed in °C, °F, mV and Ω
  • Low temperature coefficient: 10 ppm /°C for thermocouples and 7 ppm/°C for resistance
  • Measurements with HOLD function
  • Simulation of ramps, preprogrammed steps and synthetizer values
  • Correction of calibrated sensors
  • Display of minimum, maximum and average value
  • Backlight
  • 10,000 values stored and displayed graphically

Further features

Scaling in measurement and simulation modesThis function allows sensors to be corrected after a calibration. Scaling is performed using up to 10 segments, in order to fit with the real calibrated value.
Calibrated sensorsA database can be created to design curves for sensor s after calibration according to the corrections mentioned on a calibration report.
Data recordingData are recorded either manually on event or automatically with programmable frequency. Data is stored with date and time and can be displayed as list or curve.
Statistical functionsContinuous display of average, minimum and maximum value of the signal under monitoring, as well as number of measurements.
Simple and cyclical ramp generationRamps can be generated by setting low and high dwell, rising and falling times, stabilization and delay times (1 to 3,600 s). Delay time enables a single user to launch the ramp and go to the control panel.
Steps simulationThis mode allows predefined values to be sent with programmable amplitude and frequency.
SynthesizerThis mode allows predefined values to be sent with programmable frequency.
