Dayton Type J Thermocouple Probe 18 in

The Dayton 36GK75 is a Type J thermocouple probe with an ungrounded junction and a mini plug connector. It is built for measuring temperature in air, gas, or liquid applications. The probe body measures 1/8 inch by 18 inches and includes a cable length of 18 inches. It offers 1/4 inch MNPT and 1/8 inch MNPT process connections.

Suits technicians needing an ungrounded Type J

This probe suits technicians who need an ungrounded Type J sensor with a mini plug for direct connection to compatible meters or controllers. The dual MNPT thread options allow installation in different port sizes. Buyers who require a grounded junction for faster response, a different thermocouple type such as Type K, or a longer cable run should look at other models.

Temperature range -346 to 2,913 °F (-210 to 1,200

The probe covers a temperature range of -346 to 2,913 degrees Fahrenheit, which equals -210 to 1,200 degrees Celsius. This wide span lets it handle cryogenic liquids as well as high-temperature processes. Verify that your instrument accepts Type J input and that the mini plug matches your device before ordering.

Questions about this item

How do I verify the probe reads correctly after installing it in a 1/4 in MNPT or 1/8 in MNPT fitting?

Apply a known temperature source within the -346 °F to 2,913 °F range and confirm the mini plug output matches the expected Type J millivolt curve for that temperature.

What ships with the probe and what must I supply separately?

The 18 in ungrounded Type J probe with mini plug is included; mating mini jack, extension wire, and any thread sealant for the 1/4 in MNPT or 1/8 in MNPT connections are not included.

Which probe length should I choose for my application?

This model is offered in an 18 in probe length; select it when the sensing tip must reach 18 in into the air, gas, or liquid stream.
