Why should I choose a waterproof scale?

IP68 is the highest waterproof rating sold by Marsden. It makes the DS-781SS perfect for challenging environments, and where it needs to be regularly washed down to keep it hygienic. It also means it can be used to weigh product that may be wet or contain moisture, such as fish.

The DS-781SS is typically used in environments such as fishmongers and butcher shops.

A stainless steel scale also looks more professional to your customers than plastic retail scales, which can be prone to water ingress, greatly reducing their lifespan. Stainless steel is more resistant to corrosion, too.

Why is this scale Trade Approved?

It is a legal requirement that all scales used in the buying and selling of goods are Trade Approved. Since this is the purpose of retail scales, they must always be Trade Approved.

Trade Approved scales are subject to far more tests and checks than standard scales in order to ensure the customer is getting value for money. It also ensures weight readings are repeatable (i.e there is no discrepancy between readings if the same item is added to the scale again).

All the retail scales sold by Marsden are Trade Approved and have verification fees included in the price. Read more about Trade Approved scales in this blog post.

What are the benefits of the DS-781SS?

Aside from its IP68 waterproof rating, a key benefit of the DS-781SS is its portability. Four non-rechargeable C-sized batteries provide a massive 600 hours of continuous operation. The scale can be mains operated if desired - an AC adaptor is included.

This weighing scale has a capacity of 15kg, with an accuracy to the nearest 2g (up to 6 kilos) and 5g (to 15 kilos). It is also price base switchable - showing product price per kilo, or per 100g.
