Type J Thermocouple Probe
The Dayton 36GK97 is a Type J thermocouple probe built for measuring air, gas, or liquid temperatures in HVAC systems. It features an ungrounded junction and a standard plug for direct connection to compatible instrumentation. The probe sheath measures 3/16 inch in diameter by 18 inches long, with an 18-inch cable lead. It is supplied new and ready for installation.
Sustained Temperature Range
This probe operates continuously across a range of -346 to 2,913 degrees Fahrenheit, or -210 to 1,200 degrees Celsius. The ungrounded design isolates the sensing junction from the sheath, reducing electrical noise and preventing ground loops during long-term monitoring. This construction supports stable, repeatable readings in harsh environments where the sensor remains immersed in the process media for extended periods.
Installation and Common Issues
The probe installs via integrated 1/4 inch and 1/8 inch male NPT threads, allowing direct mounting into standard pipe fittings without separate compression fittings. Ensure thread sealant is rated for the full temperature span to avoid leaks at extreme limits. The transparent cable jacket lets you inspect for heat degradation or moisture ingress, which are the most frequent causes of signal drift or open-circuit failure over time.

Questions about this item
Does the 18 in probe and cable stay cool enough to handle during long high-temperature runs?
The probe is rated from -346 °F to 2,913 °F, but the cable and standard plug are not rated for the full probe temperature; keep the plug and cable outside the hottest zone.
What thread fitting must my process port have for the 1/4 in MNPT connection?
The probe includes a 1/4 in MNPT fitting; your port needs a matching 1/4 in FNPT thread to seal properly.
Will the standard plug on this Type J probe connect directly to my older panel meter?
The probe terminates in a standard Type J plug; it mates with any instrument that accepts a standard Type J connector.
