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.

This is the probe - and then what do I need to connect this to a datalogger?

Asked by: Dan160
Hi Dan, you're going to want a connector. Part number SMPW-CC. Please see attached link: https://www.omega.com/en-us/sensors-and-sensing-equipment/temperature/thermocouple-and-rtd-connectors/p/SMPW-CC

What gauge is the thermocouple wire itself? Does it vary based on probe diameter (e.g. for the 1/16" diameter)?

Asked by: Paul82
Hi Paul, Yes wire gauge of the probe is determined by the probe diameter. For this spec please refer to spec page for "XL-K-MO". You will find wire gauge vs probe diameter there. Best regards OMEGA
