Aquaya Institute CBT EC+TC Kit MPN Calculator

Our friends at the Aquaya Institute designed an interactive tool to automatically determine Most Probable Number (MPN) test results for the CBT EC+TC Kit by just the touch of a screen.

Simply tap a compartment if the same compartment in your sample is blue/blue-green.

You can tap your screen online or download the file to use the MPN Calculator offline.

This tool is especially helpful for new users of the CBT EC+TC MPN Kit and for individuals who are new to water quality testing.

Aquagenx gives its sincere thanks to the Aquaya Instutute for developing this tool that simplies on-site testing in the field!
