ALTF 02 is a cost-saving tube contact resistance thermometer with passive output, in
an impact-resistant plastic housing with snap-on lid, incl.strap.
Surface contact sensors are electric contact thermometers used for surface temperature measurement on
solids, having at least one so-called contact area that is brought into contact with the surface to be measured.
This surface contact temperature sensor measures the temperature of a medium flowing inside a pipe (e.g.
the water temperature). This tube surface sensor is used for measuring temperature on piping and tubes
(e.g. cold-water and hot-water), wor on heating sections for heating system control.
