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.
- Meets EN ISO 7027.
- Automatic overall range adjustment with Standard-Set T-Cal.
- High accuracy.
- Laboratory and mobile use.
- Real-time clock.
- Waterproof sample chamber and housing.
- Keypad: conditional acid and solvent resistant; membrane switch keypad with audible feedback.
- Auto-Off: automatic switch off approx. 20 min after last key press.
