Thermocouple Probe Type J
The Dayton 36GK74 is a Type J thermocouple probe designed for measuring air, gas or liquid temperatures in HVAC systems. It features a 1/8 inch by 12 inch probe with a mini plug connection for direct instrument attachment.
Connection and Range Limits
The probe offers dual 1/4 inch and 1/8 inch MNPT fittings for installation flexibility across different port sizes. Its ungrounded junction provides electrical isolation, while the 12 inch cable length restricts the distance between the sensing point and the reading device.
Temperature Range Decides Fit
This probe operates from -346 degrees to 2,913 degrees Fahrenheit (-210 degrees to 1,200 degrees Celsius), covering most standard HVAC and industrial process requirements. Buyers needing a wider span or a different thermocouple calibration must select an alternative model.

Questions about this item
How do I choose between the 1/4 in and 1/8 in MNPT fittings on this probe?
Select the 1/4 in MNPT for standard process ports and the 1/8 in MNPT where space is limited; both thread into the same 1/8 in diameter probe body.
What does the -346 to 2,913 °F range mean when the probe is installed in a machine?
The ungrounded Type J junction measures air, gas or liquid across the full -346 °F to 2,913 °F span with electrical isolation from the sheath.
What does the mini plug connection cap in practice?
The mini plug carries the Type J thermocouple signal to any instrument with a matching miniature jack, limited only by the probe's 12 in cable length.
