This handy hand-held pocket meter checks your Reverse Osmosis membrane performance. Simply turn it on and dip the end in a glass of water – it instantly give you a reading of TDS (total dissolved solids). To check membrane performance, test untreated water and then your RO water. Compare the results to determine the percent of removal. Most people replace the membrane when removal drops below 85%
