Larger surface checks benefit from a probe that creates stable contact and gives the user enough reach to position the sensor safely. The TP755 family measures contact surface temperatures up to 300 °C and uses Type K Class 1 thermocouple construction for compatible thermocouple instruments.
The Ø 27 mm contact surface supports direct measurement on larger surfaces, while the 300 mm stem length provides practical distance between the handpiece and the measuring point. Tolerance according to IEC 60584-2 gives users a defined basis for assessing readings.
The family includes a straight version and an L-shaped TP755/9 version. Both versions have a 2 s response time, supporting efficient surface temperature checks where fast sensor reaction helps keep inspection work moving.
The probes use Type K thermocouples with Chromel (Ni-Cr) and Alumel (Ni-Al) conductors.
The probe family is designed for direct contact temperature measurement on surfaces.
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.
Both versions have a 300 mm stem length and Ø 27 mm contact surface.
TP755/9 has an L-shaped measuring head with a 50 mm offset for surface contact in less accessible positions.
The thermocouple tolerance follows IEC 60584-2, with Class 1 accuracy.
