The GO-Sys ISA is calibrated to provide readings of many parameters - primarily Chemical Oxygen Demand and Total Organic Carbon. A reagent free calculated value can a useful measurement option. The GO-Sys ISA nicely complements the wet chemical analysers - providing a different measurement technique.

Photometers and Test Kits

Nanocolor test kits

Envitech offer a range of photometers, ancillaries and test kits from German manufacturer, Macherey Nagel. The Nanocolor range includes:

Total Organic Carbon

Biological Oxygen Demand

Chemical Oxygen Demand

Many of the parameters measured using the Nanocolor kits only require a pipette and a photometer to complete the process, but those listed above generally require additional equipment such as a digestion block. Full details of how to carry out the test is included on each separate test-kit page on our website under the 'instructions' tab. This will include references to additional equipment needed.
