As it is impossible to manufacture all components (and typically electronics, screws, etc). in our own premises, the choice, sourcing and incoming quality control are extremely important.
Through screening of the market, manufacturers, experiences in other industries we select components that could show an interest and test samples. We are constantly testing all type of components from diaphragms, to screws and electronics. When potential is found we undergo long term testing and if the component show and advantage we may decide to use it.
Therefore our products are constantly made from the best, most accuracy and most reliable components available in the world.
Note that this is only possible with the flexibility of manufacturing by hand. More industrialised manufacturing processes see their reactivity drop significantly.
