Surface temperature probe

The TEST PRODUCTS INTERNATIONAL CK13M is a Type K thermocouple designed for surface temperature measurement in industrial and HVAC applications. It connects via a mini plug to compatible meters and data loggers. The exposed junction provides direct contact with the target surface for responsive readings.

Simple connection and common pitfalls

The mini plug inserts directly into a matching Type K input without tools or adapters. Ensure the plug polarity matches the instrument to avoid reversed readings. The exposed tip is fragile; avoid bending the probe sheath or crushing the junction during installation. Secure the cable to prevent strain on the connection point.

Type K range and environmental limits

The probe operates from -58 to 1,202 degrees Fahrenheit and -50 to 650 degrees Celsius. Accuracy depends on the meter calibration and the quality of surface contact. The 39/64 inch by 4 inch probe size limits access to confined spaces. The 3 foot 3 inch cable length restricts the distance between the measurement point and the instrument.

Questions about this item

How can I verify the CK13M probe reads correctly after connecting it?

Plug the mini connector into a Type K thermometer, touch the exposed tip to a surface, and confirm the display falls within the -58 °F to 1202 °F range.

What comes with the CK13M and what must I supply?

The probe with its 3 ft 3 in cable and mini plug is included; a compatible Type K thermometer or data logger is required separately.

Which temperature range version of the CK13M should I select?

This model covers -58 °F to 1202 °F (-50 °C to 650 °C); choose it when your application stays inside those limits.
