Electronic Scales
Electronic scales can weigh material with unparalleled precision. And there are countless occasions of when precision is vital. This might be because you are weighing jewels, something which can be done with small electronic scales but there are also situations when mass needs to be weighed precisely on a large scale.
An example is when pallet trucks need to transport very heavy material. Transporting heavy goods has its risks and therefore each pallet truck has a maximum capacity. In this situation electronic scales are vital so that too much mass is never weighed onto the truck.
Because pallet trucks are used outside these electronic scales need to be waterproof. This just goes to show that electronic scales are so widespread and advanced these days that they are used in industry in this way, and can even be built to be waterproof.
