An integral high accuracy Pt-1000 probe continuously monitors liquid temperature allowing temperature compensation and future calculation of kinematic viscosity. The technology proves high accuracy of measurement and long term calibration stability even in severs operation conditions. It is insensitive to plant vibration, high variation of temperatures or turbulence. A choice of wetted parts materials: from stainless steel for general industrial use, Ni-Span-C for most demanding applications, and Hastelloy for applications where ultimate corrosion resistance is required.
