The In-Line Dual TDS Monitor DM-1 is a high-precision digital meter designed to measure the Total Dissolved Solids (TDS) levels of water before and after filtration.
Featuring dual sensors and a simple switch system, it allows users to easily check the difference in water quality at both the inlet and outlet of a filtration system.
Ideal for managing filter replacement schedules, the DM-1 is compact, easy to install with 1/4-inch quick fittings, and powered by a long-lasting microprocessor-controlled system for accurate and efficient readings.
