Series 520 PB Balances

Series 520 PB Analytical and Precision Balances

Swiss idea, Swiss development, Swiss production.

With over 40 years knowledge and experience, Precisa Gravimetrics AG has developed one of the most important innovations in weighing technology in recent years. The Precisa PHASTbloc™ weighing cell allows you to benefit from this advanced technology and provides a technically perfect, easy-to-use, attractive, economical and sustainable balance.

Discover the innovations of the 520 series. We look forward to inspiring you – as many users have been already.

Timeless and proven in everyday practice

Five high-quality mechanical membrane keys guarantee longevity and a tactile feel with clearly noticeable feedback to the user.

The Model 520 PB is also suitable for laboratories, the pharmaceutical, food, light and consumer goods industries as well as production or for pharmacies and jewellery.

Wherever precise and demanding routine work is carried out on a regular basis, reliability and user-friendliness are key components. State-of-the-art with an extensive range of applications such as counting, density, animal weighing etc.

Including statistics, a wide range of languages, RS232 and USB interfaces, all current and future requirements are met.

It has never been so easy to choose the right balance.
