Turbidity meter TB 211 IR
The compact infrared turbidity meter TB 211 IR is designed to allow fast, precise on-site testing. The unit measures the scattered light at an angle of 90°, as stipulated in EN ISO 7027. The wide measuring range from 0.01 to 1100 TE/F = NTU = FNU permits use of the unit for various media, ranging from drinking water to waste water.
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
