Overview
The AF25 is a contact sensor for measuring the surface temperature of cold or hot water pipes and other curved surfaces. It has a 1 m connection cable and a brass strap with a contact tongue, and the 6 mm probe is 35 mm long. It is a passive sensor, so it connects directly to a controller input. Eleven versions cover Pt100, Pt1000, Ni1000 and several NTC elements, plus an LM235Z version.
