The Fluke 2638A incorporates the Fluke patented Universal Input Connector to bring more accuracy to thermocouple measurements than most other instruments in its class. The Universal Input Connector supports 14 common thermocouple types. Temperature-focused menu selections make the 2638A especially suitable for temperature validation applications. If you need to “zero” a large number of thermocouples to a known reference temperature before starting a temperature profiling or validation test, the 2638A will normalize all readings to your reference channel at the push of a button and store the offsets for reference in a supporting data file. If you are conducting chamber tests, heat treating tests under AMS guidelines, or validating temperature devices under 21 CFR regulations, Hydra Series III makes it that much easier to comply.
