A turbidimeter is a device used in the laboratory to measure turbidity; its function is to evaluate the amount of particles suspended in a liquid, essentially measuring the amount of light that is reflected through it. The measurement essentially gives us information about the cleaning of the liquid and can also identify possible impurities present in the sample; these measurement tools are of utmost importance for laboratories, as they allow for fast and accurate analyzes, especially in food, water and other industrial products.
Features of Turbidimeters and Classes of turbidimeters for laboratory use:
Modern turbidimeters consist of a light source (usually LED lamp) and a detector that measures the degree of turbidity of the liquid; several different types of turbidimeters are available for laboratory use.
These include:
- LED Lamp Turbidimeters: These turbidimeters are based on one or more blue LED lights to illuminate the sample, the amount of reflected light from the sample is measured and becomes a detected turbidity reading. These devices deliver accurate, fast readings under an integrated design.
2. Pulsed Light Turbidimeters: These devices are based on a pulsed light process to calculate the turbidity of a sample, pulsed light turbidimeters are effective in detecting turbid liquids with lower detection limit than traditional turbidimeters. They also offer increased reach and improved behavior in variable environments.
3. Saci Lamp Turbidimeters: These devices use solid lamp beam light technologies to measure turbidity, the measurement is done by scanning the solid lamp light through the sample.
Another class of turbidimeter that can be used in laboratories for turbidity measurement
This technology offers more accurate measurements with increased detection in liquids that are outside the scope of measurement of straight line devices. 4. DIGITAL AND MICROSCALE TURBIDIMETERS: These devices are used for measurements under the smallest turbidity scale (NTU).
They are able to detect cloudy liquids and impurities more accurately than previous devices, providing much more detailed measurements, these devices can measure between 0.02 and 0.05 NTU, allowing extremely accurate measurement.
Fiber optic turbidimeters for more detailed measurement
In addition to the aforementioned types of turbidimeters, there are also models available that use fiber-optic technology to measure liquid turbidity. These devices have a variety of applications in water measurements and pollution assessments.
They use fiber-optic portions inside the device to convert light to turbidity measurements, which are ideal for situations where highly accurate and fast measurement is required.
Advantages for scientists when choosing the turbidimeter for their need
In conclusion, there is a wide variety of turbidimeter devices available for laboratory use, depending on the application, scientists can choose between LED lamp devices, pulsed light, SACI solid lamp and optical fiber, as well as digital and microscale devices.
These devices provide accurate, fast, and effective measurements for a variety of applications.
