microLAN, based in Waalwijk, the Netherlands, is a company specialized in early warning systems for water quality monitoring, based on optical measurements. The company started in 2003 as a trade agency for water quality measuring equipment, including lab and online testing for aquatic toxicity and algae monitoring. In 2014 microLAN took over a patent for automated on-line monitoring of enzymatic activities in water which it applies for monitoring bacterial water pollution. Through this addition microLAN could add the BACTcontrol to its existing product line with a full range of fully automated online monitoring devices for guarding the quality of drinking and surface water.
