Direct surface temperature checks need a probe that reacts quickly and fits the measuring point without unnecessary setup. This Type K surface thermocouple supports contact measurements up to 300 °C, giving technicians a practical solution for routine checks on surfaces and components.
The fiberglass cable helps with handling near warm surfaces, while the 2 s response time supports fast reading during inspection work. Tolerance according to IEC 60584-2 and Class 1 thermocouple construction provide a defined basis for dependable measurement results.
The family covers cable lengths from 1 m to 20 m, making it easy to select a probe for nearby handheld work or for measuring points that are harder to reach. Available versions include TP647, TP647/2, TP647/3, TP647/5, TP647/10 and TP647/20.
The probe uses a Type K thermocouple with Chromel (Ni-Cr) and Alumel (Ni-Al) conductors.
The T0.63 response time describes the sensor reaction to a temperature change, reaching 63% of the total signal variation during contact with a metal surface at 200 °C.
The measuring tip is designed for direct contact with surfaces during temperature checks.
The probe is supplied with a fiberglass cable for connection between the measuring point and instrument.
The family includes 1 m, 2 m, 3 m, 5 m, 10 m and 20 m cable versions.
The thermocouple tolerance follows IEC 60584-2, with Class 1 accuracy.
