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)
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.
