The water quality is essential when reprocessing medical devices. It is recommended to use completely demineralised water and to monitor and document the water quality for mid-cycle rinse as well as the final rinse in the WD. A result of an insufficient water quality are hazards as limescale and pitting corrosion. High-quality water ensures a retention of the material properties of the instruments and WDs.
To measure the conductivity and determine the water consistence (pH value, water hardness) test strips as well as electronic test equipment can be used. Water parameters are determines in the standard DIN EN ISO 15883 part 1 Washer Disinfectors as well as in the standard DIN EN 285 Steam sterilisers (for boiler water).*
In this section, you will find various test equipment and analysers that support you in this case:
