HVAC thermocouple probe Type K

The Dayton 36GK95 is a grounded Type K thermocouple probe built for measuring air, gas or liquid temperatures in HVAC and industrial systems. It connects via a standard plug and fits 1/4 in or 1/8 in MNPT process connections.

Sustained temperature measurement

The probe operates continuously from -325 °F to 2,280 °F (-200 °C to 1,250 °C) with an 18 in cable and 3/16 in diameter sheath, allowing stable readings during long duty cycles without drift from short-term spikes.

Grounded junction for fast response

The grounded junction design delivers the quickest thermal response in the Type K range, making this probe the right choice when reaction speed outweighs electrical isolation requirements.

Questions about this item

Does the 18 in cable stay flexible and accurate when the probe runs at 2280 °F all day?

The probe is rated from -325 °F to 2280 °F, so continuous operation at the top end stays within its specified range.

What thread fitting must my pipe or vessel already have for the 1/4 in MNPT or 1/8 in MNPT probe to seal?

You need a matching 1/4 in FNPT or 1/8 in FNPT port; the probe includes both MNPT sizes for direct installation.

Will the standard plug on this Type K probe connect to my older digital thermometer that uses a mini-plug?

No, the probe terminates in a standard Type K plug; a mini-plug instrument requires an adapter or a different probe.
