以斑点鱼作为探测生物，检测水样对鱼的移动速度、游动高度、转身活动、环游频率和死亡数量的影响。仪器利用摄像和图象分析技术连续检测被测样品对鱼的活性的影响，进而确定其毒性强弱。

the modern bbe fish toximeter observes fish in a fish tank flowed through by a stream of "sample" water. tracking all movements online the instrument records any change in behaviour. as a result of an accident the toximeter triggers an alarm at an early stage of exposure. this uncomplicated but sensitive instrument is designed for the surveillance in water bodies such as

the bbe fish toximeter is well suited for the rapid detection of wilful or negligent damage to water systems.

technology for water quality monitoring

continuous biological monitoring with the bbe fish toximeter enables rapid detection of toxic substances in water and provides an online early warning system. live video camera images are recorded with a digital camera and analysed online by an integrated pc. toxicity computations and assessments are based on the measurement of the following behavioural parameters:

speedspeed distributionheightdistancescircular motionsnumber of active fish

the behaviour of the fish is examined permanently and analysed for significant changes. a combined parameter - the toxic index - is calculated. this method allows superior statement about the condition of the monitored water compared to other monitoring instruments.

different parameter settings are se-lectable adapted to the demands of the monitoring. adjustments are easy to perform and do not need expert knowledge.
