The turbidity meter TUM 50 is a portable device for measuring turbidity according to ISO 7027. This allows the user to quickly and easily determine important water parameters with the turbidity meter and to check the quality of drinking water and waste water. The calibration of the turbidity meter TUM 50 is very easy due to the calibration standards supplied. The calibration can be carried out with 7 preset points. In addition, user-specific calibration points can also be set. The turbidity meter is capable of measuring turbidity of liquids up to 2000 NTU.


Furthermore, the measuring unit can be switched to EBC (European Brewery Convention) or ASBC (American Society of Brewing Chemists). The measured values ​​are displayed on the large color display. The turbidity meter is mainly used in the laboratory and is therefore operated with a plug-in power supply. Via the rear USB interface, the turbidity meter can be connected to a computer and the memory can be cleared.


What is the EBC or European Brewery Convention? (See above in the picture gallery) As EBC, the color or the color intensity of beer and wort is described in Europe. This set value describes how much light is absorbed by beer with a certain original wort content. The turbidity meter can determine this value and thus helps in judging the type of beer.
