The Series 520 PT with its 5″ touch screen as standard provides clear and simple visualisation, intuitive operation and customisation options. In addition to the touchscreen, the model has 6 fixed keys for the most common operating functions: on/off, tare, print, user and application selection. The intelligent system alerts the user when the PT model balance needs levelling. To reset the position of the balance correctly, a levelling guide is displayed on the screen. It shows which direction the feet need to be moved. Quality is assured with support for minimum sample weight according USP chapter 41, Audit trail according FDA 21 CFR Part 11 and Alibi memory (as part of EC-verification).

The PB model features a simpler design with an LCD and five high-quality mechanical membrane keys which guarantee longevity and a tactile feel with clearly noticeable feedback to the user. The keys structure the various application possibilities in a user-friendly manner and considerably improve the operation of the device. Wherever precise and demanding routine work is carried out on a regular basis, reliability and user-friendliness are key components.
