ToxProtect II
Quick and reliable detection of toxins in the water supply
The ToxProtect II is an automated monitoring system to protect a drinking water supply from accidental or malicious contamination due to harmful substances. The characteristic of these threats is a relatively high concentration of dangerous substances that occurs suddenly. Such situations must be detected quickly and safely. False alarms are reduced to an absolute minimum—improving the trust of the operators and reducing unnecessary expenditure.
The Measurement Principle
The ToxProtect II continuously monitors the swimming activity of up to 10 fish in an aquarium fed with drinking or mains water. Fish are sensitive to the presence of toxins, exhibiting a change in their behavior. The movements of the fish cause interruptions in the instrument’s light barriers which register the entire volume of the aquarium. Fish activity (interrupts per minute per fish) is calculated from these interruptions. An alarm verification system is activated if values fall below a predetermined threshold.
Toxicity Detection
The ToxProtect II detects changes in the swimming activity of the fish due to intoxication and evaluates the measurement data for alarm events. The ToxProtect II detects for example the respiratory toxin potassium cyanide within 10 minutes at a concentration of 1 ppm.
Alarm Verification
In order to prevent false alarms due to naturally occurring variations in fish behavior, the ToxProtect II implements a verification system by decreasing the illumination (turning the light off) inside the aquarium during the verification period. Under normal conditions, this would lead to a dramatic increase in fish activity. However, under toxic conditions, this may be different. Hence, monitoring the variation in activity during modified illumination makes it possible to automatically accept or reject the initial alarm.
PC Software – exclusive data evaluation
One or several ToxProtect II instruments can be monitored remotely by transferring data to the optional PC software via LAN, GSM modem, or the internet. The software offers several possibilities for the display and analysis of all measurement values. It is also possible to define different parameter settings and check the current status of the instrument remotely.

Algae Toximeter II
An instrument for the fast and sensitive detection of toxic substances in water
The bbe Algae Toximeter continuously monitors water for the presence of toxic substances. Standardized algae are mixed with the sample water and the instrument detects the photosynthetic activity of the algae. Damage to the algae, caused e.g. by herbicides, causes a reduction in algae activity and activates an alarm above a pre-defined threshold.
Product Features
- 1-2 chamber systems with up to 10 daphnia each
- Sample preparation: ultrasonic filter unit
- Automatic daphnia feeding with ready prepared algae food
- Compact housing: IP54 security protection class
- Separate compartment for flow through cell and electrical components
- Modern touchscreen PC
- Alarm evaluation with bbe alarm database software
- Hardware diagnostic
- Remote control via software (Optional)
Applications
- Drinking water supply
- Dam monitoring
- Waterway analysis and assessment
- General environmental assessment
- Intake monitoring
- Chemical analysis
- Limnological work
- Research and education
Daphnia Toximeter II
Sensitive detection of toxic substances in water via computer-assisted digital image analysis
The bbe DaphTox II observes daphnids, commonly known as “water fleas”, under the influence of constantly running sample water. Based on the Extended Dynamic Daphnia Test, bbe developed a new sensitive method to detect hazardous compounds in water from rivers (source-water protection), plants, distribution systems, and production drains to preserve human health and to monitor water.
