The idea that waterproof scales are only suitable for places that use water are a myth, consider a bakery or pie shop owner often using scales with holes below the top plate allowing flour dust to enter - which can be a breeding ground for bacteria.
Waterproof scales are both dust tight and waterproof meaning you can do a deep clean and thoroughly washed down they incorporate stainless
steel parts and watertight seals and suitable for industries such as food and beverages,
powders, chemicals, pharmaceuticals, or for any application needing a
sealed scale for wet or dusty environments.
