2. Product Description
Application The AMI Turbiwell is used to measure turbidity in potable water, sur -
face water, effluents and water steam cycles.
The turbidimeter is also suitable for the measurement of other liquids
of which the turbidity correlates with the concentration of a suspend -
ed solid or an emulsified liquid, e.g. oil in water. See chapter ppm
Calculation, e.g. “Oil in water”, p. 48 for details.
