DM-2

The DM-2 is a high-performance commercial-grade monitor designed to measure Total Dissolved Solids (TDS) levels in both input (feed) water and output (product) water of a water filtration system. With advanced features such as Auto-Off functionality and robust construction, the DM-2 is ideal for use in Reverse Osmosis (RO) and Deionized Water (DI) systems. Its wide-ranging applications include drinking water filtration, water treatment, aquariums, hydroponics, and more.

Key Features

1. Advanced Microprocessor Technology
   Ensures highly efficient and accurate TDS measurements.

2. Dual TDS Monitoring
   Displays TDS levels for both feed water and product water using in-and-out electrode probes.

3. Auto-Off Function
   Conserves battery life by automatically shutting off after 3 minutes of inactivity.

4. Factory Calibrated
   Pre-calibrated using a 342 ppm NaCl solution. Features digital calibration for added convenience.

5. Diagnostic Error Messaging
   Identifies system errors to streamline troubleshooting.

6. Shielded Sensor Cables
   Improves signal accuracy and reduces interference.

7. Quick-Connect Fittings
   Includes two 1/4″ T-fittings for easy installation (also available in 3/8″ or 1/2″ fittings).
