Rated 5 out of 5 by from Well Made Bought these to use with Omega Thermocouples. They appear to be well made and easy to connect to thermocouple wiring. Nice that they come with a "locking" wire to keep them connected to the thermocouple. Like the space for labeling the connectors.

Why the narrow temperature range for the K of -29C to 180C? Can these be used outside this range with maybe somewhat reduced accuracy? if so how bad is it? or does it not work well enough to be useful?

Asked by: bill4711
Thank you for your inquiry. This an Operating Temperature Range. The body of the connector is rated for -29°C to 180°C.
