Are there a list of compatible thermocouple probes to use with these wells? Is there one that is used with a 1/2 NPT plug style connection? (threaded on one side, flat on the other)

Asked by: Sharktooth13
Thank you for your inquiry. These thermowells are supposed to be used with our NB series thermocouple probes with industrial heads. For more questions, please email temp@omega.com or call 1-888-826-6342.
