Versa Flex – Checkweigher

Improve efficiency and profitability with checkweighers designed for dry applications. The Thermo Scientific™ Versa Flex Checkweigher and the Thermo Scientific™ Versa Flex GP Checkweigher are ideal for weighing a wide range of packaged food, pharmaceutical and personal care products in dry applications, but easily integrate into operations that already use Versa checkweighers. From light to heavy-weight packages, both the Versa Flex (fixed height) and Versa Flex GP (height-adjustable cantilever) checkweighers improve accuracy and reliability while decreasing product giveaway.

The Versa Flex and Versa Flex GP Checkweigher line targets dry applications such as baked goods, snack foods, prepared foods, condiments, pastas/rice/beans, baking ingredients (flour, sugar, etc.), personal care products such as diapers, soaps and creams, as well as pharmaceuticals.
