Description 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 7ppm/°C in resistance), IP54 protection and robust design, TC calibrators are suitable for...

Thermocouples G, D: For specifications, refer to the instruction manual (Available on request) Accuracy is given for reference @ 0°C. When using the internal reference junction (except couple B) add an additional uncertainty of 0.3 °C at 0 °C. It is possible (thermocouple B excepted) to choose by programming the cold junction 50-52 Avenue Paul Langevin, F-91130 Ris Orangis - Tél. : 01 69 02 88 88 - Fax : 01 69 02 04 38
