The TURBISENS probe is used to measure the turbidity of a liquid.
It is designed for measurement in immersion, in tanks or open channels.

Turbidity expresses the clarity or transparency of a liquid, such as water, based on the presence of suspended particles that scatter and absorb light. The more turbid a liquid is, the less transparent it becomes.
The measuring principle is based on a combined transmitted light / scattered light measurement according to DIN EN ISO 7027,
One receiver is facing the transmitter at 180° for transmitted light measurement. A second receiver is positionned at an angle of 90° for scattered light measurement.
Transmitted light measurement is used for high turbidity values, it is usually referred to with the unit FAU.
Scattered light measurement is used for low turbidity values, it is usually referred to with the unit FNU or NTU.
A measuring range 0-100g/l SiO2 solids concentration can be selected, which works only by means of transmitted light measurement.
