Online Laser Turbidimeter for Drinking Water

Understanding Turbidity

Turbidity refers to the degree of obstruction caused by suspended matter in water when light passes through. These suspended solids can include soil, sand, fine organic and inorganic matter, plankton, microorganisms, and colloidal substances. The turbidity of water is influenced not only by the content of these suspended substances but also by their size, shape, and refractive index. Generally, the higher the turbidity, the cloudier the water appears.

Turbidity Standards

Turbidity detection limits vary based on the water supply source and purification techniques used. For urban and rural domestic water supplies, the turbidity detection limit should not exceed 1NTU under normal circumstances and should not exceed 3NTU if the water source and water purification technical conditions have restrictions. For small-scale centralized water supply and decentralized water supply in rural areas, the turbidity detection limit should not exceed 3NTU under normal circumstances and should not exceed 5NTU if the water source and water purification technical conditions are limited.

Daruifuno's OLTU600 Digital Laser Turbidimeter

Daruifuno's OLTU600 digital laser turbidimeter is designed with a compact, miniaturized design that requires minimal installation space and is conducive to integration. The OLTU600 laser turbidity digital sensor utilizes a 660nm laser light source with high resolution and fast response. Optional features such as a viewing window and automatic emptying system reduce maintenance workload. The injection flow rate requirement is low, minimizing the amount of waste liquid generated during measurement. The Turbidity Sensor supports offline calibration and is plug-and-play, with internal storage of calibration data.
