Insertion Turbidity Probe Model AP2

Description:

The turbidity probe model AP2 measures the NIR- absorption caused by turbidity in liquids.

Configurable to measure:

ppm, mg/l, EBC, FTU, g/l, %, AU, Ext, OD, ….

Measuring principle Turbidity Probe:

The probe uses the principle of NIR- absorption to detect turbidity in liquids. An LED light source with emission in the near-infrared range and a high-precision receiver diode are installed in the sensor’s optics.
The measurement in the infrared spectrum ensures precise measurement results, unaffected by fluctuations in product color.
