Wuxi Daoxin Technology Co., Ltd. proudly presents the DX-NTU3000, a high-precision Online Turbidity Meter designed for continuous, stable, and low-maintenance monitoring of turbidity levels in water. The system accommodates a full-range measurement capability from 0 to 1000 NTU, offering a resolution of 0.01 NTU in low-range conditions and 0.1 NTU for higher turbidity values.
The instrument utilizes the nephelometric 90° scattered light method for turbidity detection, a widely accepted standard in global water quality monitoring. This allows for accurate assessment of suspended particles in various water samples. The DX-NTU3000 supports both LED and laser light sources, giving users the flexibility to balance performance with cost and maintenance needs.
A key strength of this device lies in its smart design: built-in temperature compensation (0–80°C) eliminates temperature-related drift, while anti-bubble optics and a rugged 316 stainless steel sensor housing ensure long-term stability, even in high-load or aerated media. Its IP65-rated construction makes it suitable for challenging field conditions.
The system offers industry-standard outputs (4–20mA, RS485 with Modbus RTU) and is easy to integrate into SCADA or distributed control systems. Users can choose from multiple installation options, including flow-through, immersion, or flange-mounted setups, making the DX-NTU3000 adaptable to diverse application environments.

Engineered for versatility, the DX-NTU3000 serves in numerous sectors where turbidity measurement is essential to performance, quality, or regulatory compliance. In drinking water treatment plants, it helps utilities continuously monitor water clarity, ensuring safety before final distribution.
In wastewater treatment plants, the DX-NTU3000 monitors critical process steps such as flocculation, sedimentation, and filtration. Its fast response time (≤10s) and dual-alarm system enable immediate corrective action when turbidity levels deviate from norms.
The analyzer is equally valuable in the food and beverage sector for process water management and quality assurance. In cooling tower systems or manufacturing rinse water loops, turbidity monitoring helps prevent fouling, corrosion, or process failures.
In environmental surveillance, the DX-NTU3000 provides real-time data on the turbidity of rivers, lakes, and reservoirs—allowing early detection of runoff events, pollution incidents, or seasonal variation trends. It also finds use in aquaculture, supporting optimal breeding conditions through clean water control.
Pharmaceutical and electronics industries, where ultrapure water is required, benefit from the analyzer’s fine resolution and stability, ensuring consistent compliance with strict process standards.
Wuxi Daoxin Technology offers robust support to ensure the long-term performance of the DX-NTU3000. From product selection to post-installation maintenance, our technical experts are available to guide users through every stage of deployment.
