SM554 is suitable for use in all areas of industry.

The partly insulated probes is suitable for use with all conductive liquids especially high viscous material and adhesive products for example soap, ketchup, cheese, Etc.

It’s also suitable for low viscosity products like water and acids

Its compact shape makes it the best solution for level limit in these applications.
