Precisa balances are prime examples of Swiss precision, accuracy, and reliability.

They are tried and tested in both demanding laboratory environments and industrial applications and are subject to rigorous quality controls throughout the entire manufacturing process. Precisa invests continuously in developing new technologies and the result is a state-of-the-art range of precision instruments for the most exacting demands.

Self-Calibration System

The analytical balances contain an innovative adjustment system, meaning you will always have a perfectly adjusted weighing scale.

The system operates automatically or manually and detects all changes in the environment by time including temperature and air pressure change.

We have designed the mechanical system in such a way that the internal weights are protected against liquid, dust, and any foreign particles. This also confirms the weighing accuracy.

Our 390 series analytical balances promise you the best possible performance and precision.

Stability-Indicator

Visually Predictive.

Our new optical stability indicator provides visual indication of disturbances within the environment and provides real time information about the balance environment. The indicator displays how the weighing accuracy develops in your daily working environment and reduces potential uncertainties.

The stability tracker display simply indicates to the balance user when the analytical balance has high ambient stability and takes longer to change with greater instability.

Now, by observing the orbital symbol, you can intuitively predict a weighing result quickly or wait until the completion of the circle so that the weighing result is definitely fixed.

Draft Shield Protection

This was one of the topics at the hearts of our Swiss engineering team. The new door automation system is simple, yet very impressive.

Electronically powered side doors with timing-tuned, high-efficiency motors, ensure a gentle, smooth, and precise opening to a desired position. Together with the door design, the state-of-the-art draft shield is optimized to prevent any interference when weighing in fume hoods or ventilated laboratory rooms.

Our weighing chamber is designed in a way that neither powder nor liquids can contaminate the weighing system. The bottom plate is equipped with a tear-off edge preventing liquids from penetrating inside the casing.

All draft shield parts, top and side glasses, and weighing pan, can easily be removed without any tools, and placed into your lab dishwasher. The sophisticated door design without any guide rails or channels provides an affordable, easy to clean solution.

Efficient Touchscreen

All balance functions are available at your fingertips on this smart and bright color touchscreen. With built-in color logic, all the touch active surfaces – marked by a key or a selection are drafted in blue. The balance user interface is intuitive and easy to operate. Tap on the touch active, blue colored button and swipe with ease. There is no way to get lost with the “Home” button that is always available, which takes you conveniently back to the start.
