DM-1

The DM-1 In-Line Dual TDS Monitor by HM Digital is a user-friendly device designed to measure and compare Total Dissolved Solids (TDS) levels in two water lines simultaneously. Ideal for applications involving reverse osmosis (RO) and deionized (DI) water filtration systems, the DM-1 ensures optimal water quality by monitoring both feed (input) and product (output) water.

TDS levels indicate the amount of salts, minerals, and other substances dissolved in water, providing a clear assessment of water purity. This compact monitor is suitable for various applications, including potable water systems, aquariums, hydroponics, and industrial processes like food and beverage production.

Key Applications

1. Home Use: Ensure drinking water is properly filtered and safe for consumption.
2. Aquariums: Maintain clean water for aquatic life by monitoring TDS levels.
3. Water Filtration Systems: Assess the efficiency of water filtration systems.
4. Commercial Use: Ideal for industries where water quality plays a critical role, such as food and beverage production.
