GermanyWTWTurbidity measuring instrumentVisoTurb700Using the scattered light colorimetric method, in accordance withENISO 7027According to the standard regulations, the testing range is very wide, including turbidity measuring instrumentsVisoTurb 700from0to4,000FNUIt has an automatic range switching function, which reduces the resolution to 0.001FNU. Turbidity measuring instrumentVisoTurb700Equipped with advanced and reliable ultrasonic cleaning components, the probe can operate reliably for a long time with minimal maintenance. Turbidity measuring instrumentVisoTurb700Before leaving the factory, it undergoes strict multi-point testing and does not require calibration for on-site use.

Principle of turbidity testing

Turbidity is caused by suspended particles in water, which diffuse and reflect back into the incident light. Typically, this is achieved through90The scattered light in that direction is used as the test signal, and the unit measured in this way is calledNTU. UseFormazineThe unit measured by the instrument after calibration with standard solution is calledFNUThis method is suitable for testing low to medium ranges, from0.01to4000 FNUThe scope. according toEN27027andISO7027Standard, adopted860nmInfrared light, as a light source, is not affected by the chromaticity of the sample.

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.
