Laboratory turbidimeter TB 300 IR

Turbidity is measured according to ISO 7027 by nephelometric means (90° scattered light). The infra-red light-source permits measurement of coloured and colour-free samples. The automatic measurement range detection facility (Autorange) enables direct turbidity measurement from 0.01 to 1100 NTU.

• Automatic overall range adjustment with standard set T-Cal
• High accuracy
• Suitable for laboratory and mobile use
• Memory storage of up to 1000 data-sets
• Real-time clock
• Waterproof sample chamber and housing
