Liquid Analysis Description
Why This Turbidity Sensor
Unlike conventional turbidity sensors that are sensitive to color interference and signal drift, this sensor adopts a dual-beam infrared scattered light photometric design to ensure consistent performance even in complex water conditions.
For procurement teams and system integrators, this means:
-
Reduced calibration frequency
-
Lower maintenance costs over the product lifecycle
-
Stable data output for control and monitoring systems
-
Reliable operation in long-term continuous measurement scenarios
This turbidity sensor is well suited for projects where data reliability and operational stability are critical.
Turbidity Sensor Measurement Technology & Performance
The sensor operates using the ISO 7027 infrared light scattering principle, which minimizes the influence of ambient light and sample color. The dual-beam optical structure enhances measurement consistency and improves resistance to optical contamination.

How does this turbidity sensor reduce the influence of water color?
This turbidity sensor is based on the ISO 7027 infrared scattered light method, which minimizes the impact of sample color by using infrared wavelengths instead of visible light. This makes it suitable for complex water conditions where color interference is common.
Is the turbidity sensor suitable for continuous online monitoring?
Yes. The sensor is designed for continuous online measurement and offers stable output, good repeatability, and built-in self-diagnostic functions to ensure reliable long-term operation in industrial and environmental monitoring systems.
What is the difference between low and high turbidity versions?
The low turbidity sensor is optimized for high sensitivity and low flow conditions, while the high turbidity sensor is designed for harsher environments with higher flow velocity and pressure. Each version uses different materials and mechanical structures to match its application range.
Can this turbidity sensor be integrated into existing control systems?
The sensor supports RS485 communication, making it suitable for integration with PLCs, controllers, and upper-level monitoring systems commonly used in water treatment and industrial automation applications.
How is sensor maintenance handled in high-fouling environments?
An optional automatic wiper cleaning function is available to reduce fouling on the optical surface. This feature helps maintain measurement stability and significantly reduces manual maintenance requirements.
Does Instrava support customization or OEM integration for this turbidity sensor?
Instrava provides customization and OEM support, including measurement range selection, material options, cable length, and integration requirements. Engineering support is available to ensure compatibility with specific system designs and applications.
