The MW500 water tester replaces the older SM500 unit and offers many distinct advantages compared to the previous model.
This ORP meter reads the negative millivolt (MV) numbers required when doing water demonstrations for Enagic, Tyvent in any of the other water machines that create negative ORP.
You must purchase the MA9025 oxidative kit for this to work when doing your demonstrations as this will oxidize the probe allowing proper negative readings of your water.
Many of the Enagic dealers use this when they are doing their shows to show the differences in oxygen redox potential of the Kangen Water® that is produced by the machines that they are demonstrating.
