What is a turbidimeter?

A turbidimeter is an analytical instrument used to measure the clarity or turbidity of a liquid sample by quantifying the number of suspended particles or solids present in the solution.

 

How does a turbidimeter work?

GAO Tek turbidimeters emit light into a sample and measure the scattering and absorption of light caused by particles suspended in the liquid. The amount of scattered light is then correlated to the turbidity level of the sample.

 

What units are used to measure turbidity?

Turbidity is commonly measured in NTU (Nephelometric Turbidity Units) or FNU (Formazin Nephelometric Units), depending on the instrument and calibration standards used.

 

What are the applications of turbidimeters?

Our turbidimeters are used in various industries such as water treatment plants, environmental monitoring, beverage production, pharmaceutical manufacturing, and research laboratories to assess water quality, monitor sediment levels, and ensure product quality.

 

Why is turbidity measurement important?

Turbidity measurement is crucial for assessing the quality of water and liquids. It helps in monitoring the effectiveness of water treatment processes, ensuring compliance with regulatory standards, and detecting changes in water clarity that might affect processes or product quality.

 

How accurate are turbidimeters?

The accuracy of our turbidimeters can vary based on the instrument’s quality, calibration, and measurement range. High-quality instruments with proper calibration can provide accurate turbidity measurements.

 

Can turbidimeters measure color in addition to turbidity?

Some advanced GAO Tek turbidimeters may also be capable of measuring color in addition to turbidity, providing a more comprehensive analysis of liquid samples.

 

How are turbidimeters calibrated?

GAO Tek turbidimeters are typically calibrated using reference standards with known turbidity levels. Regular calibration ensures accurate and reliable measurements.

 

What are the different types of turbidimeters?

Our turbidimeters can be classified into various types such as benchtop models, portable handheld units, online or continuous monitoring systems, and process control instruments, each suited for specific applications and environments.

 

Are turbidimeters used for regulatory compliance?

Yes, GAO Tek turbidimeters are often used to ensure compliance with regulatory standards set by organizations like the Environmental Protection Agency (EPA) for water quality monitoring and treatment.
