I used this tester to test the effectiveness of the deionization system for window cleaning. There were streaks on the windows after the initial deionized water cleaning, so tests were conducted to determine why this was happening. The results were very satisfactory and proved that the system works very well. The windows that needed washing turned out to be a problem as they hadn't been cleaned in so long they needed extra attention to remove all the grime that had accumulated over the years. The device worked perfectly.
