HM Digital (DM-2) Industrial Inline Dual TDS Meter-Monitor; 1/4" JG
DM-2 Industrial Inline Dual TDS Meter
Monitor feed and product water quality in real-time with precision dual-probe TDS measurement for commercial and industrial reverse osmosis systems
The HM Digital DM-2 delivers simultaneous monitoring of incoming tap water and outgoing purified water through dual inline probes, giving you continuous feedback on system performance and filter efficiency. With ±2% accuracy across a 0-9990 ppm range and 46-inch shielded waterproof cables, this industrial-grade meter is built for demanding commercial applications including carwash systems, window washing rigs, manufacturing lines, and food processing facilities.
Built for Commercial Reliability
Dual TDS Display
Simultaneous monitoring of feed and product water with separate in and out electrode probes. Extra-large LCD shows both readings at once.
Quick Installation
Pre-fitted with 1/4" John Guest quick-connect T-fittings. Drop into any standard RO system line in minutes without tools or thread tape.
Industrial Design
Water-resistant casing built stronger than the DM-1. Variable mounting bracket adapts to any installation position. Shielded cables resist wear and moisture.
Precision Calibration
Factory calibrated to 342 ppm NaCl. Recalibrate each probe independently or both simultaneously with included mini-screwdriver adjustment.
Dual Range Accuracy
Reads 0-999 ppm in 1 ppm increments, then 1000-9990 ppm in 10 ppm increments with blinking x10 indicator. ±2% accuracy throughout.
Extended Battery Life
Auto-off after 20 seconds conserves power. Two AAA batteries included deliver over 1000 hours of continuous monitoring between changes.
Commercial and Industrial Systems
The HM Digital DM-2 installs on any reverse osmosis or deionization system using 1/4" tubing with John Guest fittings (also available in 3/8" configuration). Ideal for commercial carwash spot-free rinse systems, window cleaning pure water systems, manufacturing process water monitoring, food and beverage processing, aquarium and hydroponics facilities, laboratory water systems, and large-capacity residential RO installations. Use it to verify membrane performance, determine filter change intervals, and provide customers with continuous system feedback.
HM Digital meters are factory-tested and calibrated to professional laboratory standards, trusted by water treatment professionals in industrial applications worldwide.
