Fast & simple measurement of microalgae on substrates The unique instrument for quick and easy phytobenthos measurements Direct measurement without preparation

Rapid and simple determination of green algae, cyanobacteria and diatoms on different substrates. The bbe BenthoTorch is a robust, water proof field instrument for rapid quantification of green algae, cyanobacteria and diatoms on different substrates such as sediments and stone surfaces. A measurement is performed in less than 15 seconds. Just turn it on, place on the substrate and read off the results.

Why should we measure benthic algae? Various algal species and cyanobacteria have adapted their nutrient uptake systems enabling them to survive in shallow water close to the shoreline. Here the sunlight still penetrates down to the sea or river bed. This habitat is home to benthic algae, ranging from the microscopic to the gigantic kelp. Especially microphytobenthos attached to the subsurface, play an essential role in primary production. For the assessment and improvement of surface water the European Water Framework Directive stipulates to determine phytoplankton including benthic APPLICATIONS...

Operation The BenthoTorch is simply switched on either by shaking or by use of a magnetic INSTRUMENT SOFTWARE FUNCTIONS rod. Four contact keys are well arranged for operating the BenthoTorch. An intelligibly presented menu enables one-step measurement. The illuminated Start and stop of measurement display gives clear readings of results even in bright sunlight. After starting a Access to all stored data measurement, all steps are processed automatically: the countdown, the LED tuning and display of the results. A vibration signal informs the user about completion of the measurement. Settings:...
