Dayton 36GL12 Thermocouple Probe Type J

SKU CH-9RW1-AKMDT

Type J thermocouple probe with grounded junction, standard plug, 6 in cable, -346 °F to 2,913 °F range

  • Type J thermocouple measures up to 1,200 °C
  • Grounded junction gives fast response in air, gas or liquid
  • Dual 1/4 in and 1/8 in MNPT threads fit multiple ports
  • Standard plug enables quick instrument connection
  • 6 in probe and cable suit compact installations

Application Range

The Dayton 36GL12 is a Type J thermocouple probe built for measuring air, gas or liquid temperatures in industrial machinery. Its grounded junction and standard plug suit maintenance engineers and process technicians who need a direct replacement sensor. Buyers who require a different thermocouple type or a non-grounded junction should look elsewhere.

Sustained Measurement

The probe operates continuously from -346 Degrees to 2, 913 Degrees F (-210 Degrees to 1, 200 Degrees C) without drift. The 1/8 in x 6 in probe and 1/4 in MNPT or 1/8 in MNPT threads install directly into existing ports for stable, long-term readings.

Thermal Response

A grounded tip transfers heat quickly so the sensor follows rapid temperature changes in the medium. The six-inch cable keeps the plug clear of hot surfaces while the rugged construction resists vibration in motor and pump environments.

Questions about this item

How much heat can the Type J probe withstand during continuous operation?

The probe operates from -346 to 2,913 degrees Fahrenheit or -210 to 1,200 degrees Celsius, so it handles sustained high-temperature exposure within that range.

What process connection must my system provide for the 1/4 in MNPT fitting?

The probe requires a female 1/4 inch NPT threaded port; a 1/8 inch MNPT option is also listed if your port matches that size instead.

Will the standard plug on this probe connect to my existing Type J instrumentation?

Yes, the standard plug follows the Type J colour code and pin layout, so it mates directly with any compatible Type J meter or controller you already use.
