It is a sensitive instrument for the detection of toxic compounds in water bodies such as rivers, water treatment plants intakes and sewers. The instrument B il md mzweispaltig 125 is based on a development of the Extended Dynamic Daphnia Test (EDDT), a proven method used widely in Europe and other parts of the world. Continuous biological monitoring with the bbe Fish Toximeter enables rapid detection of toxic substances in water and provides an online real-time early warning system. The relative magnitude and presence of the toxic substances is recorded by the instrument to enable further analysis. This unique instrument thus enables supervision and control of water sources in order to detect, record and respond rapidly to incidents of toxic bb e Fish Toximeter pollution and contamination. : for detection of a wide range of toxins The Fish Toximeter is well-suited to the detection of wilful or accidental damage to water systems such as the drinking Online evaluation movement enables rapid assessment of water supply.

Toxic events are clearly indicated as "alarms". A statistical approach enables alarm recognition even under difficult real-world conditions such as "noise" or slow drift in the measured curve(s). The senstivity of the alarm can be pre-defined or easily adjusted based on the specific application. The bbe software is an approved system and already in use with other online toxicity assessment systems.
