Measurement Principle
The turbidity meter uses an infrared LED light source (850 nm) and dual photodiodes (90° and 180°) for measuring turbidity via scattered light (low range) and transmitted light (high range), ideal for both clear and colored liquids.
Measurement Units
Readings are displayed in NTU (Nephelometric Turbidity Units), compliant with ISO standards. Compatible with FTU, JTU (1 NTU = 19 JTU), and SiO₂ units (1 NTU = 7.5 SiO₂ units).
