HM Digital (DM-2) Industrial Inline Dual TDS Meter-Monitor; 1/4" JG

HM Digital (DM-2) Industrial Inline Dual TDS Meter-Monitor; 1/4" JG

HM Digital Professional Grade

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

✓ 0-9990 ppm Range ✓ Factory Calibrated ✓ 1/4" Quick-Connect ✓ Industrial Casing

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.

KEY FEATURES

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.

COMPATIBILITY & APPLICATIONS

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.
