PTU200 Turbidity Meter for Drinking Water/Portable Water Turbidity Measurements

Introduction

The PTU200 Turbidity Meter utilizes an optical scattered light detection method to quantify turbidity by measuring the intensity of light scattered by suspended particles in water. This approach provides stable and repeatable readings across a broad range of water conditions. Built with industrial operation in mind, the PTU200 supports continuous online measurement, minimizing the need for manual sampling and laboratory testing.

Equipped with configurable outputs and a clear display interface, this meter can integrate with automation systems such as PLCs, SCADA, and distributed control frameworks. The result is a versatile solution that supports precise turbidity tracking and process transparency, enabling faster detection of anomalies and more responsive operational control.

Working principle

The PTU200 turbidity device with an effective turbidity sensor measures turbidity based on how suspended particles scatter light within the fluid. The key elements of its working principle include:

• Light Emission: A stable light source projects a beam into the water sample.

• Particle Interaction: Suspended particles cause the light to scatter at various angles.

• Optical Detection: Photodetectors positioned around the sensor collect the scattered light.

• Signal Conversion: The intensity of the scattered light is converted into an electrical signal that corresponds to the turbidity level.

This optical method allows the instrument to produce consistent measurements even when water color or sample composition varies, making it highly suitable for online applications where conditions change dynamically.
