Industrial temperature probe

The Dayton 36GL08 is a Type K thermocouple probe built for air, gas or liquid measurement in HVAC and process systems. Its ungrounded junction reduces electrical interference while the standard plug connects directly to compatible meters or controllers.

Thermal range and response

The probe operates from minus 325 degrees Fahrenheit to 2,280 degrees Fahrenheit, covering cryogenic to high-temperature applications. A 24 inch cable keeps the instrument away from heat sources and the 3/16 inch diameter sheath fits tight ports without restricting flow.

Mounting and integration

Threaded 1/4 inch and 1/8 inch MNPT fittings let the probe screw into existing pipe taps or thermowells without adapters. The transparent colour allows visual confirmation of sensor position while the standard plug frees the installer from proprietary connectors.

Questions about this item

How do I install the 1/4 in MNPT thermocouple probe without damaging the threads?

Wrap PTFE tape on the 1/4 in MNPT threads, hand-tighten into the port, then finish with a wrench no more than one extra turn; over-tightening crushes the 3/16 in probe sheath and shifts the ungrounded junction.

What maintenance does the Type K probe with standard plug need over time?

Inspect the 24 in cable and standard plug for cracking or discoloration after every few hundred hours at 250 °C; replace the probe once drift exceeds your process tolerance because the ungrounded junction cannot be field-calibrated.

At what temperature does the 24 in Type K probe hit its limit first during continuous use?

The upper limit is 1,250 °C (2,280 °F); sustained exposure near that temperature degrades the insulation on the 24 in cable before the ungrounded junction itself fails.
