AQUAUDR® Sensitive water hardness test strips include all the same benefits as the classic AQUADUR® test strips, but feature a special, very low measuring range. 

The test strips are the perfect tool whenever very low amounts of water hardness have to be safely detected. The test strips are for example successfully used in dialysis centers to check feed water, so that the sensitive reverse osmosis units are not damaged by excess water hardness. 

AQUADUR® Sensitive water hardness test strips are also CE marked according to the directive for medical products 93/42/EWG.
