Thermocouple Calibrator "AOIP" Model TC6621

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/C in thermocouples and 7 ppm/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  1µV (TC 6621) and 1 (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
