Water Quality Meter DM4000

All-in-One Water Quality Analysis with the Water Quality Meter DM4000 (pH, CD, Salt Meter)

Simplify field and lab testing with the Water Quality Meter DM4000—a versatile, handheld instrument that simultaneously measures pH, Conductivity (CD), and Salinity in a single, rugged device. Engineered for environmental monitoring, aquaculture, hydroponics, food processing, and water treatment applications, the DM4000 delivers fast, accurate, and reliable multi-parameter results—eliminating the need for multiple meters and reducing testing time by up to 60%.

Engineered for Efficiency, Accuracy, and Durability

The DM4000 Water Quality Meter features three integrated sensors in one probe or a multi-connector system, providing real-time readings with laboratory-grade precision:

pH: 0.00 to 14.00 pH (±0.01 pH accuracy) with Automatic Temperature Compensation (ATC)
Conductivity (CD): 0 to 200 mS/cm (auto-ranging) with ±1% full-scale accuracy
Salinity: 0.0 to 200.0 ppt (±0.5% accuracy), automatically calculated from conductivity
Its IP67 waterproof housing, backlit LCD, and ergonomic design make it ideal for use in wet, dusty, or outdoor environments—from rivers and farms to processing plants and labs.

Triple-Parameter Measurement in One Device – pH, conductivity, and salinity with automatic cross-compensation.
Automatic Calibration (1–3 Points per Parameter) – Recognizes standard buffers and conductivity solutions for quick setup.
IP67 Waterproof & Shock-Resistant – Withstands splashes, rain, and temporary submersion; floats if dropped in water.
Replaceable Sensors with Quick-Connect – Easy maintenance and individual sensor replacement to reduce long-term costs.
Long Battery Life (500+ Hours) – Auto-off function; uses standard AAA batteries for field convenience.
Data Hold & Min/Max Tracking – Freeze readings for recording; monitor parameter extremes over time.

Trusted Across Water-Dependent Industries

From checking irrigation water salinity and hydroponic nutrient strength to monitoring wastewater discharge or verifying seafood brine concentrations, the DM4000 supports EPA, HACCP, and ISO compliance with consistent, traceable data. Its intuitive interface requires minimal training—making it perfect for technicians, farmers, aquaculturists, and educators.

Whether you’re managing a shrimp farm, testing drinking water, or optimizing fertilizer use, the Water Quality Meter DM4000 gives you a complete water profile—in seconds.

One meter. Three critical parameters. Total water insight.
