The DM-2 Commercial Dual Inline TDS Meter from HM Digital has a stronger water resistant casing than the DM-1. This tool monitors the TDS of your reverse osmosis system in two places and lets you know exactly how the system is performing.

DM-2 features include:

  • Especially designed for commercial/industrial applications.
  • Stronger, water-resistant casing.
  • Each water line can be individually calibrated.
  • Backlit Display
  • Extra large, easy-to-read LCD display.
  • Longer, waterproof, shielded cables.
  • Variable mounting bracket.
  • Uses two standard AA Batteries 

 

BulkReefSupply.com suggests installing the dual TDS meter post membrane and post DI stage. These two readings will notify you when it's time to change the RO membrane and DI resin. This unit features a digital display and comes with two 1/4" GA Murdock Quick Connect Tee's with double o-rings to ensure a proper seal. As with all HM-Digital products, the DM-2 comes factory calibrated.

The DM-2 is an upgrade to the DM-1 TDS Meter:

I noticed my batteries are getting pretty low on this unit. Do you know what batteries it takes? It would be helpful to know before I take it apart. Thanks!
