What is a Turbidity Meter?

Now to begin with, if you want to learn about turbidity meters. You first need to know everything about turbidity. What is turbidity for you? Generally, turbidity is nothing but the cloudy appearance of water. Usually, this cloudy look of the water is mostly caused by suspended solid particles. Turbidity is just a measure of the clarity of the water. Turbidity helps you to identify. And measure the quality of water for you to drink. Now, just like many people even you would be wondering why turbidity is important. Turbidity is mostly important because it helps you identify the presence of bacteria and other particles. And to keep that water at a safe level for you. There are water treatment plants to keep your water safe. In addition to that, turbidity is also important in the industry to measure efficiency. Thus, turbidity meters are one of the popular tools you might have heard of. This tool is mainly used to monitor the water quality in lakes, rivers, drinking water, and mangroves. Before measuring turbidity was done by the Secchi desk. In simple words for you, this disk is black and white. And has a rope to check the transparency of water. Here, the disk is placed horizontally in the water until it becomes invisible. The rope scales the depth of visibility. That measures the transparency of water. The second method used was the Jackson turbidity unit. In this method, you have to comprise a glass vessel and a candle mounted below it. To use this method first you have to pour the water into this vessel. You have to put this vessel until the flame is covered properly. Here the more water you need to add is the more transparency your water has. However, this measurement was not that accurate. And to have more accuracy in the measurements, turbidity meters were built. And with the help of the turbidity meters, you can measure it precisely.

How Does the Turbidity Meter Work?

Generally, if you are someone who wants to learn about the working of turbidity meters. Then you are in the right place. Starting with, the turbidity meter helps in measuring the transparency of the water. This electronic Turbidity meter measures the amount of light. This is light is separated by the suspended particles at 90°. Now, this scattering varies with the size of particles. In simple words, with the large size particles. The light will scatter at smaller angles. On the other hand, with the small size particles. You will see that light is scattered at large angles. As a result, some turbidity meters state the ratios and non-ratios as specifications. Now to make up for the differences in the size of the particles. This meter uses detectors of different ranges. Furthermore, your turbidity meter measures the ratio. It will likely use the data from many other detectors. After using the data it calculates the average. This helps in correcting the change that is caused by the size of particles.
