Overview

The DM‑2 commercial in‑line dual TDS monitor provides reliable, real‑time water quality monitoring by measuring the total dissolved solids in both source and purified water streams. Built with advanced microprocessor technology, this robust device not only delivers precise TDS readings but also incorporates features like automatic shut‑off to conserve battery life and diagnostic messaging for troubleshooting. Factory digital calibration ensures consistent performance right out of the box, and shielded sensor cables help maintain accurate readings in a range of environments. Thanks to its commercial‑grade construction and easy‑to‑read display, the DM‑2 is well suited for use in reverse osmosis and deionization systems, potable water treatment, aquariums, hydroponic systems, and other settings requiring continuous water quality assessment.
