with Infrared Light Source (EN ISO 7027)
- Range 0.01 - 1100 NTU
- Measurement with infrared light at an angle of 90°
- Measurement of coloured liquids
- Easy handling
- 600 tests without battery change
The compact Lovibond infrared turbidity meter TB 210 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 - 1100 TE/F = NTU = FTU makes the instrument suitable for various applications, ranging from drinking water to waste water.
As infrared ligth is used for measurement purposes, 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.
