Turbidity and suspended solids are two important indicators for water quality monitoring. Online testing of turbidity and suspended solids usually uses infrared light scattering method, which is mainly used in surface water, aeration tanks, tap water, circulating water, sewage treatment plants, sludge reflux control, and discharge monitoring.

New turbidity and suspended solids concentration measuring instrument
VisoTurbandViSolidThe successful launch of the probe has been announcedWTWTruly possessing their own optical sensors, namely turbidity and suspended solids probes. These probes are equipped with advanced and reliable ultrasonic cleaning components, ensuring that the probes can operate reliably for a long time with minimal maintenance.WTWThe turbidity probe adopts the scattered light turbidity method, which is consistent withENISO 7027Standard regulations. The suspended solid probe adopts the scattered light testing method. Another major feature of the above-mentioned probes is that their testing range is very wide,VisoTurbturbidity0-4000 FNU，ViSolidSuspended solids0-300g/l SiO₂The instrument has a dynamic range switching function to achieve the best resolution. Therefore, using only two probes can test almost all samples, from drinking water to viscous sludge.

Ultrasonic automatic cleaning system

There is an ultrasonic generator on the sensor, and as long as the sensor is connected to the system, high-frequency ultrasonic signals are generated, causing the optical lens to vibrate continuously with an amplitude of several micrometers. In the center of the lens, the amplitude is large. This can prevent any form of pollutants from accumulating on the lens, ensuring continuous and reliable operation. Some calcium salts will still adhere to the probe after a long time, forming dirt that is difficult to remove even with a brush or other cleaning agents, and can only be cleaned by acid washing. Ultrasonic vibration can also prevent bubbles from accumulating in the testing area and interfering with the test, as bubbles also scatter some light.

Maintenance Province

· Compared to traditional probes with scraping blades,WTWThe surface of the probe is very smooth and flat, and dirt is not easily attached to the surface of the lens.

· The continuous ultrasonic cleaning system prevents pollutants from adhering to the probe surface from the beginning and can also eliminate bubble interference.
Therefore, this probe has a wide range of applications and can operate reliably for several weeks without any maintenance or cleaning.The sturdy structure and effective ultrasonic cleaning make our turbidity and suspended solids probes very suitable for use in environments such as sewage treatment plants. Accurate testing and low maintenance are its main features.

Testing principle of suspended solid concentration measuring instrument

As the concentration of suspended solids continues to increase, suspended particles in water will interact with each other. On the one hand, incident light cannot reach all particles, and on the other hand90The scattered light in that direction will be blocked by a large number of particles, making it undetectable. Therefore, when testing high concentrations, it is necessary to test the scattered light in the other direction in a different way.WTWTwo methods are used to test the concentration of suspended solids, and at lower concentrations60Scattered light, used at high concentrations180Degree backlit light.
