The DM-2 is a commercial grade TDS meter that will help monitor the water feeding into your RODI system, as well as the output of the RODI filter for any impurities, so you know if a carbon block, the DI resin, or TFC membrane needs to be switched out, ensuring your aquarium water is as pure as it can be.
Its shielded cables, along with diagnostic messaging, the DM-2 also works nicely within applications such as drinking water, forms of water treatment, hydroponics, and other uses.
