Good Water (PrecipSol4-32) #4 - 32 OZ Isopure Water Reverse Osmosis Systems3431 The 442-150qt calibration solution is

The 442-150qt calibration solution is compatible with most Myron L conductivity meters and multi-parameter instruments designed for natural water testing

Compatible replacement for Intelifil IF-SM-AA010B — precision-engineered activated alumina media removes fluoride and inorganic arsenic from whole-house water supplies

making it ideal for membrane evaluation and POU system demonstrations

while the 60 PSI shut-off ensures consistent pressure without over-pressurizing downstream fixtures
