to get Price and Availabilty of the configuration you need.

Probes up to 48 inches in length are shipped "straight." Probes over 48 inches are shipped "coiled". If probe above 48 inches in length must ship straight, please add "-SST" to the end of the part number, and add $75.00 to the probe cost. Additional shipping fees from carrier may also apply for non-standard length packaging.

Rated 4 out of 5 by from Robust Thermocouples These thermocouples held up well to the abuse we put them through during a trip to Argonnne National Labs including heating beyond their recommended operating window. The replacements that we ordered were delivered right on time according to the lead time on the website. Well done Omega.

Where throughout the probe is the temperature taken from? From the tip of the probe or is it an average? This is concerning a temperature measurement that may vary based on the exact point that is being measured. thanks!

Asked by: jennyscience
Thank you for your inquiry! The hot junction is where the temperature is detected, and it's located at about the first quarter-inch of the probe.

Do the bodies for the SCAxx-125y-6 have screws to open the body in order to replace/repair the probe?

Asked by: MWighton
Yes, you can remove the two screws on the yellow connector cap to reveal two more screws that secure the two wires from the thermocouple to the (+) and (-) terminals on the connector.

How do I attach the mating connectors- I assume these are the nut and two piece cone shaped objects- to a new SCASS-062G-6 thermocouple? I pulled them off an old one, how do I reattach them to a new one?

Asked by: noneanddone
The mating connectors are the "female" flat-pin connectors, and they just "slide" right on. if you are referring to replacing the male connector of the original probe, then that just disassembles by two screws for the cap, and then two screws under the cap. Remove and then reverse procedure to put the new on one.
