The HM Digital DM-1 Inline TDS Meter provides a fast, accurate way to monitor the total dissolved solids (TDS) levels in both your tap (feed) water and purified (product) water. Designed for use with reverse osmosis (RO) systems, this digital tester helps you determine the effectiveness of your filtration system and indicates when it’s time to replace the RO membrane.
Featuring advanced microprocessor technology, the DM-1 ensures precise readings and easy operation. The dual-probe design displays both “in” and “out” TDS levels simultaneously, while the auto-off function conserves battery life. With quick-connect fittings and a compact T-fitting design, installation is simple and efficient.
Features:
- Measures TDS levels of feed and product water
- ¼" quick-connect fittings for fast installation
- Dual range: 0–9990 ppm (1 ppm resolution up to 999 ppm; 10 ppm above)
- Factory calibrated with 342 ppm NaCl solution; easily recalibrated as needed
- Auto-off feature after 10 minutes of inactivity
- Highly accurate readings using advanced microprocessor technology
- Ideal for monitoring RO membrane performance
