  • Introduction

An online turbidity meter is a device used to measure the degree to which water loses its transparency due to the presence of suspended particles. This is an important parameter for water quality monitoring, as high levels of turbidity can indicate the presence of pollutants or other contaminants. 

Online turbidity meters operate by shining a light through a water sample and measuring the amount of light scattered by the suspended particles. This measurement is then converted into a turbidity value, typically expressed in Nephelometric Turbidity Units (NTU). 

One advantage of the MIK-PTU300 online turbidity meters is that they provide continuous monitoring of water quality, allowing for real-time detection of changes in turbidity levels. This can be particularly useful for water treatment plants, where rapid response to changes in water quality is essential for maintaining safe drinking water. 

The MIK-PTU300 online turbidity meters are available in a range of configurations, from simple and useful devices to more complex systems that can be integrated with water treatment plant control systems. Some models also include additional sensors for measuring other water quality parameters, such as pH and dissolved oxygen. 

When selecting an online turbidity meter, it is important to consider factors such as accuracy, reliability, and ease of use. Calibration and maintenance requirements should also be taken into account, as these can affect the accuracy and longevity of the device. 

All in all, online turbidity meters are an important tool for monitoring water quality and ensuring the safety of drinking water. With the right selection and use, these devices can provide accurate and reliable measurements for years to come.
