The National Quality Mark for Assistive Technology (Nationaal Keurmerk Hulpmiddelen or NKH) helps you choose the best quality medical device. But not only that: you can also be sure that the company where you buy the device meets all strict quality requirements. Businesses that carry the NKH quality mark are guaranteed to provide expertise, reliable service and transparency. More and more organisations within this sector have the NKH quality mark; in total they serve 80% of the market in the Netherlands.
