Turbidity meter TB 211 IR
Product information "Turbidity meter TB 211 IR"
As infrared light is used for measurement, the unit can be used to test both coloured and colourless liquids. The standards required for calibration of the unit are also supplied. A second adjustment mode allows alternative adjustment with user-defined turbidity standards.
- measuring ranges from 0.01 to 1100NTU (autorange)
- measurement with infrared light at an angle of 90°
- easy operation
- 600 tests between battery charges
Scope of supply: Turbidity meter, 4 turbidity standards <0.1, 20, 200 and 800NTU, battery, USB cable (1.5 m), test vial, manual, warranty statement, case

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-CalHigh accuracySuitable for laboratory and mobile useMemory storage of up to 1000 data-setsReal-time clockWaterproof sample chamber and housingScope of supply: Turbidimeter TB 300 IR in carrying case, 1 set of turbidity standards T-Cal, 7 rechargeble batteries (AA), 1 lithium battery, main charger 100-240V, PC connection cable, 4 vials (diam. 24 mm) with lids, instruction manualSpecificationsLight source:IR-LED (860nm)Keypad:acid and solvent resistant, membrane switch keypadAuto - Off:automatic switch off approx. 20 min after last key pressDisplay:Graphic-displayUpdate:Software update via internetMemory:1000 data sets with date, time and registration no.Measuring range:0.01 to 1100NTU (Auto range)Resolution:0.01NTU (0.01 to 9.99NTU) 0.1NTU (10 to 99.9NTU) 1NTU (100 to 1000NTU)Accuracy:± 2% of measured value or 0.01 (0 to 500NTU)/± 5% of measured value (500 to 1100NTU)Ambient conditions:0 to 40°C at 30 to 90% R.H.
