Eijkelkamp Infrared Turbidity meter TB 211 IR

RM 6,898.00


This compact infrared turbidity measuring instrument TB 211 IR is ideal for fast and accurate on-site analysis. The meter is easy and quick to use and it is an accurate instrument for determining turbidity. 

It is measured as provided in EN ISO 7027, the scattered light at an angle of 90°. The wide measuring ranges from 0.01 to 1100 TE / F = NTU = FNU with a detection limit of 0.01 NTU, allows the use of the device in different areas, from drinking water to wastewater.

Since the measurements are made by means of infrared light, both coloured and collarless water samples can be measured. A direct transfer of the measurement results to a PC is through the USB interface TB 211 IR easy to set up. The necessary USB cable is already part of the delivery.
