Turbidity Meter AL450T-IR with Infrared Light Source

Turbidity is measured according to EN ISO 7027 by nephelometric means (90° scattered light). The infrared light-source permits measurement of coloured and colour-free samples. The automatic measurement range detection facility (Autorange) enables direct turbidity measurement. A large graphic display, a choice of several different languages and user-friendly operating instructions make the device extremely easy to use.
