Itemnumber: BG28000 Info: The Fish Toximeter is used for the determination of toxic compounds in water and is conceived as part of an Early Warning System (EWS) to continuously monitor water pollution. This version includes a dechlorination system for the Fish Toximeter to operate the instrument with chlorinated water. It enables continuous dosing of the dechlorination agent and control of the total chlorine content of the water. NOW with a NISE 3110 17” touchscreen panel PC built into the front fascia of the instrument above the cabinet. The PC has a 1.66 GHz processor, 1 GB, 80 GB HDD, a FireWire card, USB ports and Windows xp Professional (SP3). Principle of measurement: is based on the observation of the locomotory behaviour of fishes, including:
Observation chamber construction:
Fish tank for up to 8 fish:
Equipment:
Electrical connections of toximeter:
Hydraulic supplies:
Operation: All movements of the test organisms are recorded. Each individual is observed and analysed for discrete behaviour and interactions i.e. distance. The tank is designed to keep a school of fish in an environment which resembles their natural habitat. The system continuously measures the acute toxicity of the product water, tap water, river water etc. To gain an immediate overview or to present the instrumentation, all current movements and tracks are displayed on the in-built computer screen; a traffic light on the screen informs the user about the present status. A display (using camera recognition) informs the user about the quality of the measurement. Instrument supervision:
Status/problem control:
The system uses an easy-to-use touchscreen computer that can monitor system performance and report toxicity in real-time and locally. Communication: All archived data are easily retrievable. The system records the acute toxicity data /signals automatically and stores them on hard disk. The data have a format compatible with and/or convertible to an MS Office Excel file, or they can be exported to Excel. Data are available in a proprietary format (.dpx), (.csv) with ASCII data collected for 24 h directly via serial communications/USB Remote control:
Toxicity Detection: The system does not need to use any toxic chemicals/re-agents in normal operation It is able to convert the fish behaviour (Danio rerio) signal to acute toxicity and detect the acute toxicity of a broad variety of inorganic and organic substances. It uses algorithms for the recognition of alarm situations, mathematical and statistical analysis, outlier evaluation. Alarm recognition is based on pre-defined alarm thresholds. The system can be enabled to activate an automatic event-sampling device (optional) Consumables: It can use or is capable of adapting the use of locally available and common fish species, sizes comparable to zebra fish (Danio rerio) Feeding:
Environmental requirements:
In order to ensure proper operation of the toximeter unit, it should stand as close as possible to the connection for the water supply.
