Turbidity detector - interference and elimination of water samples

Today, Guangxi Industrial Automation - Senge Technology will talk to you about how to handle the interference of water samples and eliminate it when using turbidity detectors?

1. Color: If the color of the water sample interferes with the measurement of turbidity when the absorption band of light is at an appropriate wavelength; For high chromaticity wastewater, filtered samples can be used instead of distilled water as a blank to eliminate interference caused by color

。

2. Bubbles: Bubbles have significant interference with turbidity measurement, and can be removed using exhaust tools or ultrasonic containers.

3. Temperature: Changing the temperature of the sample may cause interference with turbidity. The sample should be measured immediately after collection and must be measured at the same temperature as the original sample.

The above is an analysis of the knowledge of turbidity detection instrument water samples by Guangxi Industrial Automation - Senge Technology.
