Silver thermocouple probe with transparent cable and standard plug, 24 inches long

Dayton

Dayton 36GL05 Thermocouple Probe Type J 24 in

SKU CH-SRSE-Z5AYA

Type J grounded thermocouple probe with standard plug for air, gas or liquid measurement up to 1,200 °C

  • Product colorTransparent
  • Type J grounded junction gives fast response in air, gas or liquid
  • 24-inch probe reaches deep into ducts or vessels
  • Standard plug connects directly to compatible meters and controllers
  • 1/4 in and 1/8 in MNPT fittings suit common process threads
  • Wide range from -346 °F to 2,913 °F covers cryogenic to high-heat tasks

Probe type and reach

The Dayton 36GL05 is a Type J thermocouple probe with a grounded junction, built for direct immersion in air, gas or liquid. Its 3/16 in diameter sheath extends 24 in, giving reach into ducts, vessels or equipment where a shorter sensor cannot sit. A standard plug provides quick connection to compatible instruments, and the probe carries 1/4 in and 1/8 in MNPT fittings for threaded mounting.

Fit for purpose

This probe suits technicians and engineers who need a single Type J sensor with standard plug termination and NPT process connections. It is not for applications that require a different thermocouple type, an ungrounded junction for electrical isolation, a miniature connector, or a sheath diameter and length other than 3/16 in by 24 in.

Temperature headroom

The probe measures from -346 °F to 2,913 °F (-210 °C to 1,200 °C), covering cryogenic liquids through high-temperature combustion and heat-treat processes. At the upper extreme the grounded junction and sheath material set the practical limit; beyond 2,913 °F a different sensor construction would be required.

Questions about this item

What type of thermocouple input must my meter or controller accept for this probe?

Your instrument must accept a Type J thermocouple with a standard plug connection.

Can I install this probe into existing 1/4 inch or 1/8 inch MNPT fittings?

Yes, the probe includes both 1/4 in MNPT and 1/8 in MNPT threads for direct installation into those fittings.

How can I verify the probe reads correctly after wiring it?

Compare the reading against a calibrated reference source within the -346 to 2,913 °F range to confirm accuracy.
