Dayton 36GK72 Thermocouple Probe Type K 18 in

Dayton Type K Thermocouple Probe

The Dayton 36GK72 is a grounded Type K thermocouple probe designed for temperature measurement in air, gas or liquid applications. It features a 1/8 inch diameter probe that extends 18 inches with an 18 inch cable terminated by a mini plug. The unit includes 1/4 inch and 1/8 inch MNPT fittings for installation. It operates across a range of -325 to 2,280 degrees Fahrenheit.

Suits technicians needing a replaceable sensor

This probe suits HVAC technicians and maintenance engineers who need a grounded Type K sensor with standard pipe-thread fittings for direct immersion. The transparent colour aids visual inspection of the cable condition. Buyers who require an ungrounded junction for electrical isolation, a different thermocouple type such as Type J or T, or a connector other than a mini plug should look at other models.

Temperature range defines the application window

The single specification that decides fit is the operating range of -325 to 2,280 degrees Fahrenheit (-200 to 1,250 degrees Celsius). This span covers cryogenic gases through to high-temperature industrial processes. If the process temperature falls outside these limits, the probe will not survive or read accurately, so confirm the range matches the intended service before purchase.
