Penetration probe for air and liquid

The Cooper Atkins 50335-K is a Type K thermocouple probe built for measuring air and liquid temperatures. Its 3/16 inch diameter tip fits into tight openings while the nylon handle resists heat during use. Technicians in HVAC, food safety and industrial maintenance can deploy it for quick spot checks or continuous monitoring. The coiled cable stays compact until extended.

Temperature range and cable reach

The probe covers -40 °F to 500 °F (-40 °C to 260 °C), giving wide headroom for freezers, ovens and process lines. A 12 inch coiled lead stretches to 48 inches when pulled, letting the operator stand back from hot surfaces. Beyond 500 °F the sensor exceeds its rated limit and accuracy cannot be guaranteed. The fixed Type K output requires a compatible meter or logger.

Type K mini-plug compatibility

The connector is a standard Type K mini-plug, so the probe works only with instruments that accept that interface. Users with Type J, T or proprietary inputs cannot connect it without an adapter. The 4 1/2 inch insertion depth suits most ducts and vessels but may fall short for deep tanks or thick insulation.

Questions about this item

Will the Type K mini plug connect directly to the meter I already own?

The probe terminates in a standard Type K mini plug, so it mates with any instrument that accepts a Type K mini connector.

How can I verify the probe reads correctly after I plug it in?

Place the tip in a stable reference such as an ice bath or boiling water and confirm the displayed temperature matches the known value.

Does the package include a meter or only the probe itself?

The box contains the penetration probe with its coiled cable and mini plug; a compatible thermometer or data logger must be purchased separately.
