Turbidity Meter TB 211 IR with Infrared Light Source

These compact infrared turbidity meters (EN ISO 7027) are 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 makes the instrument suitable for various applications, ranging from drinking water to waste water. As infrared light is used for measurement, the instrument can be used to test both coloured and colourless liquids. Calibration standards are also supplied.

Items supplied:
Basic unit, with 4 turbidity standards < 0.1, 20, 200 and 800 NTU, battery, 3 cuvettes (Ø 24 mm with lids), warranty declaration, Certificate of Compliance an instructions, in case.
