TC 6621/ 6622
Handheld temperature calibrator for thermocouples or resistive probes with memory
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 measures or generates thermocouple temperatures (16 different types) and voltage at an
accuracy of 0.02%.
TC 6622 measures or generates RTD temperatures (12 different types) and resistance at an accuracy
of 0.02%.
With a very low temperature coefficient (10 ppm/๐C in thermocouples and 7 ppm/๐C 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.
