The HM Digital SM-1 Inline Single TDS Monitor accurately measures the TDS level in your purified (product) water. It enables you to determine just how good or bad your water really is! Use the meter to determine when the reverse osmosis membrane needs replacing. 

Features:
  • Highly efficient and accurate due to its advanced microprocessor technology
  • Displays TDS levels of a single water line.
  • Auto-off function -- Automatically shuts off meter after 10 minutes of non-use to conserve battery power
  • Wide range 0-9990 ppm (From 0 - 999 ppm the resolution is 1 ppm. From 1000 to 9990 ppm, the resolution is 10 ppm, indicated by a blinking 'x10' image.)
  • Factory calibrated -- HM Digital meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver.
  • Comes equipped with Quick-Connect Tee Fitting (1/4" standard)
  • Installs quickly and easily
Use the following formula to calculate the percentage of solids (TDS) that your membrane is removing:
