Measure the tap water coming in and the purified water going out of your water filtration system.
By measuring total dissolved solids (TDS) levels of feed and product water lines simultaneously, you can compare rejection rates and gauge reverse osmosis membrane, water filter, and water purification performance.
Measuring feed and product water helps ensure your water filters are working properly.

Note: HM Digital products are calibrated with a 342 PPM NaCl or 1413 µS solution. This is suitable for most applications. However, if you are measuring samples that are consistently over 1000 PPM, it is recommended to recalibrate the meter for that specific application. TDS meters are more accurate when calibrated at levels that are as close as possible to the sample being tested (such as for hydroponics, aquaculture, tinting and dying or brackish water).
