The DX-NTU3000 Online Turbidity Analyzer from Wuxi Daoxin Technology offers an advanced and user-friendly solution for continuous turbidity monitoring across diverse water treatment and industrial processes. With a wide measurement range of 0 to 1000 NTU and precision resolution options (0.01 NTU for low-range applications), it ensures reliable and consistent results even in low-turbidity environments.
The instrument employs a 90° scattered light detection system, optimized with high-quality LED or laser light sources to meet various precision and durability demands. The integrated automatic temperature compensation system (0–80°C) corrects for temperature-induced measurement drift, maintaining stability in fluctuating environmental conditions.
Constructed with a corrosion-resistant 316 stainless steel housing, the sensor is designed to withstand harsh environments such as wastewater treatment plants or industrial cooling water systems. Its anti-bubble interference mechanism ensures the integrity of readings even in aerated or turbulent water. The analyzer supports multiple installation methods—immersion, flow-through, and flange mounting—enhancing its versatility across different site conditions.
Communication is seamless with standard 4-20mA isolated outputs and RS485 Modbus RTU protocol, ensuring compatibility with existing automation and control systems. The built-in dual relay alarm function provides early alerts for high and low turbidity thresholds, improving process safety and compliance.
