KTU310 Online Turbidity Sensor 90 ° Angle Scattering Principle Fiber Structure, Strong Anti-Interference Ability

1.Principle

The KTU310 integrated online turbidimeter is designed and made by the principle of scattering light turbidimeter. When a beam of light enters a water sample, the light is scattered by the turbidity material in the water sample. The turbidity in the water sample can be calculated by measuring the intensity of the scattered light in the vertical direction of the incident light and comparing it with the internal calibration value, the final value is output after linearization.

2.Feature

• 90 ° angle scattering principle, built-in temperature sensor
• Support RS-485, Modbus/RTU protocol
• Fiber structure, the strong anti-interference ability of external light
• The infrared LED light source, high stability
• IP68, shield, water depth, 20 meters
• Convenient, fast, stable, and easy to maintain

Tips: Historical Turbidity Measurement Method

The Jackson Candle Turbidimeter used attenuation to determine turbidity.
The historical method for measuring turbidity was the Jackson Candle Turbidimeter. Developed over a century ago, this instrument was constructed from a candle and a flat-bottomed glass tube. Much like a transparency tube, water is poured down into the tube until the candle flame is no longer distinctly visible 2. The light does not disappear completely, only the image of the flame will. This occurs when the intensity of the transmitted light is equal to the amount of light scattered by particles in the water. The more turbid the water is, the quicker the image of the flame disappears.
The Jackson Candle Turbidimeter was the first practical attempt to quantify turbidity. In addition to the instrument, a standard suspension was developed, allowing the tube to be “calibrated” to the user’s eye 31. While the scale of the turbidimeter was in ppm-silica, units for this instrument were called Jackson Turbidity Units (JTU). After formazin was invented in 1926, it was used as a new calibration standard for this method, and Formazin Turbidity Units (FTU) were adopted 31. However, even with the improvement in standards, this method was limited in scope. The Jackson Candle Turbidimeter could not detect turbidity levels below 25 JTU 2,31. It was also highly subjective as readings were based on human observation. This introduced errors based on personal perception and judgment. Other light-extinction based turbidimeters were developed, but they remained dependent on human eyesight 31. Today, these methods are considered obsolete in favor of turbidity instruments (such as meters and sensors) that offer an increased measurement range and improved accuracy.
