Dayton 36GK77 Type K probe

This thermocouple probe uses an ungrounded Type K junction for air, gas or liquid measurement. A mini plug connects directly to compatible meters or controllers. The 12 in cable and 1/8 in by 12 in probe suit tight installations. It is sold new for HVAC and process monitoring tasks.

Sustained measurement behaviour

The ungrounded junction isolates the sensor from electrical noise and ground loops during continuous logging. Rated from -325 °F to 2,280 °F (-200 °C to 1,250 °C), it maintains calibration across the full span without drift from rapid cycling. The 1/4 in and 1/8 in MNPT threads allow permanent mounting in ducts or vessels.

Thermals, noise and power

As a passive sensor the probe draws no power and generates no audible noise. The transparent sheath and rugged construction withstand the stated temperature extremes without degradation. No external supply or cooling is required, simplifying integration into existing control loops.

Questions about this item

How hot does the probe tip get during continuous use in a 1,250 °C gas stream?

The probe is rated to 1,250 °C, so the tip can reach that temperature; the 12 in cable and mini plug remain at ambient.

Which meter or controller must I already have to read this Type K ungrounded probe?

Any instrument with a miniature Type K thermocouple input will work; the probe supplies a standard mini plug.

Will the 1/4 in MNPT fitting thread into the 1/8 in MNPT port on my legacy manifold?

No, the probe offers both 1/4 in and 1/8 in MNPT threads; choose the one that matches your existing port.
