Algae Toximeter
BBE Algae Toximeter

Product Features
  • Continuously monitors water for the presence of toxic substances.
  • BBE Algae Toximeter for the precise determination of algal concentrations in water. 
  • Enables  the quantitative allocation to different spectral algal classes.
  • Measuring chamber is automatically cleaned by a piston after each measurement to prevent the growth of algae and biofilms.
  • Direct chlorophyll fluorescence corresponds to wet-chemical chlorophyll analysis
  • Determines the percentage of active chlorophyll under illumination (Genty method) and serves as a toxicity measurement
  • To simultaneously determine the content of chlorophyll according to green algae, blue-green algae, brown algae (diatoms and dinoflagellates) and cryptophytes
  • Transmission used to compensate the influence of substances which cause turbidity


Daph Tox II
BBE Daph Tox II

Product Features
  • Observes daphnids, commonly known as "water fleas", under the influence of constantly running sample water.
  • BBE Daph Tox II 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.
  • Sample water (0.5 - 2 l/h) continuously runs through the measuring chamber containing the daphnia.
  • The live images obtained using a CCD-camera are evaluated online with an integrated PC to analyse changes in the behaviour of the daphnia.
  • If the change is statistically significant, an alarm is triggered.
  • The method of image analysis enables a series of measurement methods and plausibility tests to assess the daphnia's behaviour using different criteria.
  • Observation of speed parameters: average speed, speed distribution and distance between daphnia
  • Observation of behaviour: swimming height, location and fractal dimension (measurements
  • for turns and circling movements, curviness)
  • Observation of growth: determination of daphnia size



Fish Toximeter
BBE Fish Toximeter

Product Features
  • Observes the behaviour of fish in a tank under the influence of a stream of "sample" water with the aid of a camera and continuous computer-assisted image analysis
  • BBE Fish Toximeter to detect toxic substances in e.g. rivers, reservoirs, water supply systems, water treatment plant intakes and sewers.
  • Real-time, online early warning system.
  • Continuous analysis of live video images enables rapid determination of the behaviour and health of the fish.
  • Toxicity computations and assessments are based on the measurement of behavioural parameters: swim speed, behaviour (height, turns, circular motion, etc.), determination of size, number of active fish and location of fish in the aquarium.
  • Each type of change in behaviour of the fish is investigated and analysed.
  • The so-called "Toxic Index", summarised from all behavioural parameters, is calculated permanently.
  • If the toxic index exceeds a pre-determined value for a certain amount of time, an alarm is triggered. 


Tox Protect 64
BBE Tox Protect 64

Product Features
  • BBE Tox Protect 64 to protect a drinking water supply from accidental or malicious contamination due to harmful substances.
  • False alarms are reduced to an absolute minimum.
  • Monitors the swimming activity of fish in an aquarium fed with drinking or mains water.
  • The location of up to 20 fish and their activity is monitored continuously.
  • A dechlorination substance can be added.
  • The fish species that determined by user should be however active and have a length of 4-6 cm.
  • Detects changes in the swimming activity of the fish due to intoxication and evaluates the measurement data for alarm events.
  • The thresholds for the alarm triggers can be set individually.
  • High priority of the alarm emission is given to fish at the top and bottom of the aquarium, which could indicate mortality.
  • Verification is achieved by decreasing the illumination (turning the light off) inside the aquarium.
  • Equipped with internal sensors to monitor sample flow, drain blockage, temperature decrease, accidental or unauthorised ambient light in the aquarium and high chlorine concentration.

FieldScout GreenIndex+ Nitrogen App and Board
Spectrum FieldScout GreenIndex+ Nitrogen App and Board

Product Features
  • Captures and processes images from an iPhone, iPod Touch, or iPad and instantly computes the DGCI (Dark Green Color Index) of user leaves.
  • Sensitive to low nitrogen levels in the leaves.
  • DGCI has been correlated to SPAD readings in corn at the V6 growth stage.
  • This computed SPAD index is displayed by GreenIndex+.
  • Nitrogen uptake increases dramatically at the beginning of the V6 development stage.
  • Corrective measures, based on early diagnosis of severe nitrogen deficiencies, can prevent yield reduction.
  • Digital images taken in the field typically exhibit variation due to ambient lighting, shadows and texture.
  • Green and yellow reference standards on a pink background provide contrast and aid the imaging processing software.
  • Spectrum FieldScout GreenIndex+ Nitrogen App and Board allows for images to be captured under a broad range of lighting conditions.
  • Offers digital image analysis of leaves, providing growers with an accurate, low-cost method for managing in-season fertility and helps you deliver improved yield, lower nitrogen costs, and increased profits.
