How to make real-time in situ benthic algae measurements on substrates in 15 seconds

— No sample prep!

Optimize your field sampling!

The cost-effective bbe BenthoTorch allows you to experience real-time measurement of benthic algal concentrations and optimizes field sampling by eliminating the need for random sample-taking and testing or lengthy microscopic observation.


This robust, waterproof field instrument is ideal for rapidly quantifying green algae, cyanobacteria, and diatoms on different substrates such as sediments and stone surfaces designed for the roughest conditions. 


Measurements in under 15 seconds!

Just turn it on, place it on the substrate, and read off the results. It's really that simple!


The BenthoTorch can complement sampling by showing the biomass data results on the internal display immediately after measurement.
