Dishwasher efficiency filing needs 40 stations and manual water blending fails daily? 40-station laboratory blends soft-hard water automatically and computes all four indices

The problem

Energy and water efficiency filing for dishwashers needs 40 stations per GB/T 20290 with American / European / Australian water conditions; manual water blending fails daily and 40 stations of power, flow, temperature and pressure data cannot be logged by hand. This laboratory is delivered turnkey.
