Dayton 36GK76 Type J Thermocouple Probe
This Dayton 36GK76 probe measures temperature in air, gas or liquid using a Type J ungrounded junction. It terminates in a mini plug for direct connection to compatible instruments. The 1/8 inch by 24 inch probe body fits 1/4 inch MNPT and 1/8 inch MNPT process connections. It serves technicians who need a replaceable sensor for HVAC or process systems.
Thermals and power in normal use
The probe operates from -346 degrees to 2,913 degrees Fahrenheit, covering -210 degrees to 1,200 degrees Celsius. As a passive sensor it draws no power and generates no noise during measurement. The transparent cable insulation remains flexible across the rated temperature span. Ungrounded construction isolates the junction from the sheath for faster response in flowing media.
Fit and build integration
The mini plug connects directly to meters or controllers equipped with a matching Type J jack. Dual 1/4 inch and 1/8 inch MNPT threads let the probe mount in existing pipe fittings without adapters. The 24 inch cable length provides routing slack inside panels or ducts. Buyers who need a different thermocouple type or a longer lead will require a different probe.

Questions about this item
How do I install the 1/4 in MNPT or 1/8 in MNPT threads without stripping them?
Start the probe by hand to avoid cross-threading the 1/4 in MNPT or 1/8 in MNPT connections, then tighten with a wrench on the hex flats only. The 24 in probe length means you need clearance for the full insertion depth before securing the mini plug.
What maintenance will the ungrounded Type J probe need over time?
Inspect the 1/8 in diameter sheath for corrosion or mechanical damage after exposure to air, gas or liquid media. Verify the mini plug pins stay clean and tight; thermal cycling between -210 and 1,200 Degrees C can loosen connections.
At what temperature does the probe hit its limit first during sustained use?
The Type J thermocouple is rated to 1,200 Degrees C (2,913 Degrees F) continuous; sustained operation at or above this temperature will degrade the iron-constantan junction before the cable or mini plug reaches its own limits.
