Contact temperature checks on surfaces need a probe that places the sensitive area directly where the reading matters. TP746 measures surface temperatures up to 250 °C and uses a Type K thermocouple, giving users a defined probe for work with compatible thermocouple instruments.
The 2 s response time supports quick checks during inspection or adjustment tasks. Tolerance according to IEC 60584-2 and Class 1 thermocouple construction provide a clear basis for dependable readings.
With a 113 mm stem length, Ø 12 mm stem diameter and Ø 4 mm sensitive surface, TP746 is suited to direct surface measurement where a compact contact area is required.
The probe uses a Type K thermocouple with Chromel (Ni-Cr) and Alumel (Ni-Al) conductors.
The probe is designed for direct contact temperature measurement on surfaces.
The probe has a 113 mm stem length, Ø 12 mm stem diameter and Ø 4 mm sensitive surface.
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 thermocouple tolerance follows IEC 60584-2, with Class 1 accuracy.
