HM Digital TDS Meters for Home RO
HM Digital TDS Monitors are available in single and double monitor configurations:


HM Digital Dual TDS Monitors measure the tap water coming in vs. the purified water going out of your water filtration system at any time.

Single TDS Monitors, ideal for any water filtration system including reverse osmosis systems, coolers and more, display TDS level of a single water line.

Benefits of HM Digital Home RO TDS Monitors:

  • Install on a home RO System to measure and display the TDS levels of the purified product water and/or incoming feed water.
  • Highly efficient and accurate due to its advanced microprocessor technology.
  • Auto-Off function conserves battery power.  The monitor shuts off automatically after non-use.
