Designed for long-term use
where economy is a factor, NHXH
economy connectors are ideal for
high-temperature applications.
NHXH connectors are permanently
dot-coded to conform to ANSI
standards. For applications such
as high vacuum furnaces where
contamination would adversely
affect the process, UHXH
connectors are shipped with a
removable color-coded dot.

Temperature is limited only by
the hardware. CHROMEGA®­ALOMEGA®, Iron-Constantan and
CHROMEGA®-Constantan alloys
can be used at temperatures
up to 650°C (1200°F) and
Copper-Constantan can be
used accurately over its entire
calibration range of 399°C (750°F).
Noble metal calibrations are limited
by the compensating alloys to
ambient use of 260°C (500°F).
No damage will be done by
exposure to higher temperatures,
but accuracies may exceed limits
of error if a temperature gradient
exists across the connector.
