The operational temperature range of this general-purpose gauge series extends to 150°C. The gauges are temperature compensated for mild steel, stainless steel and aluminum. The gauge backing is color-coded according to the temperature compensated material type in the same method as for the F series. The gauge backing is thin and flexible, thus allowing easy adhesion on curved surfaces to provide superb performance in measuring resistance change and thermal output. Newly, 350-ohm UF series are included in addition to conventional 120-ohm's.
