EXpure 191 is a highly accurate compact NIR turbidity sensor for monitoring processes with very low turbidity, e.g. in water applications. It is well suited for swimming pool applications, as well as for some special measuring points in the drinking water sector. The measuring principle used is a 90° scattered light measurement.
