DW-2100P Series Multi-Parameter Inline Analyzers for Drinking Water
The DW-2100P Series are multi-parameter inline water analyzers designed as turnkey monitoring solutions for clean water applications such as drinking water networks, secondary supply, decorative pools, and swimming water.
They provide accurate, real-time measurement and data logging of ultra-low turbidity, free chlorine, pH, and temperature in a compact, easy-to-install, panel-mounted format with a touchscreen display and built-in data logger.
The system integrates two advanced Pyxis Lab® smart sensors:
-
The ST-765SS-FCL measures free chlorine, pH, and temperature with built-in pH and temperature compensation up to pH 9.0, delivering reliable oxidizer readings compliant with USEPA 334.0 — without membranes or extra reagents.
-
The LT-739 ultra-low turbidity sensor uses a flat quartz surface for easy cleaning, with a range up to 40 NTU and a resolution of 0.001 NTU, meeting EPA 180.1 and ISO 7027 standards.
The FR-200 Dual-Sensor Flow Reservoir helps reduce bubbles and solids for stable, high-resolution measurement and easy maintenance.
Key Features:
- Highly accurate turbidity, chlorine, pH & temperature measurement
- Self-cleaning flat electrodes reduce fouling
- Simple back-panel design for quick installation
- RS-485 Modbus, 4–20 mA, and TCP-IP connectivity
- Factory-tested and calibrated for plug-and-play startup
Typical Applications:
- Drinking & domestic water
- Decorative & swimming water
- Secondary supply
- Food & beverage process water
