Aquantic manufacture electronic fish counters based on the 'resistivity' principle and have provided over 100 systems in use throughout Europe and Canada. These pages will be added to in the future. For the moment we contain updates on our fish counter products including latest versions of the operating software and EPROM images where appropriate. Since January 1996 it has been a legal requirement in Europe that instruments such as the counters have passed an EMC (Electro-Magnetic Compliance) test. This is a check on Our RFI emissions, susceptibility to external radio fields and sensitivity to electrostatic discharge. The 2100B had to be redesigned to comply and now renamed 2100C has passed the tests and can be legally CE marked. At the moment we can only offer the 2100C for sale. Further details are availabe on the 2100C page. Historical information on our products for the last 15 years are available on the other pages.
