Measuring Principle of the Relative Turbidity Meter
An infrared diode irradiates infrared light into the media. Particles in the media
reflecting the irradiated light which is detected by the receiver diode (backscatter
principle). The electronics calculates the relative turbidity of the media according to
the received signal. One LED checks continuously the emitter luminosity and
automatically compensate if the amount of emitted light is changing, due to
Temperature effect for example. It is possible to calibrate the VOM is day light.
