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%. Highly efficient and accurate due to its advanced microprocessor technology.
Ideal for commercial use. Includes a vinyl carrying case with belt clip.
Hold Function: saves measurements for convenient reading and recording.
Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries.
Measurement Range: 0-9990 ppm. From 0-999 ppm, the resolution is in increments of 1ppm. From 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking 'x10' image.
