상세사양

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
