CALCULATOR
With the Donau Tech brand, you get premium products, the tradition with modern design as well as value for money with high quality. The range includes over 20 different models, from simple multifunction calculators to highly technical scientific calculators. They are designed for maximum ergonomics and are an indispensable tool when working in the office or when studying.
This is a mini version of the desktop calculator. Due to the small size, such a model can be easily transported in a backpack, handbag or even in a trouser pocket. With calculators, the functions can be kept to an absolute minimum and contain at most the percentage and square root functions.
But that’s exactly the purpose of this device, you can take it anywhere. In principle, it should be small, simple and functional.
