Accurate industrial thermocouple measurements
The 2638A incorporates the Fluke patented Universal
Input Connector to bring more accuracy to thermo-
couple 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 sup-
porting 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.
