Conductivity comparison

With our academic partners, we have compared our probe over time (to determine how well it remains calibrated), and as a preliminary study versus professional probes.

Both of these studies are part of work to validate citizen monitoring, and we are always looking for scientists/researchers/students to collaborate with.


This device has been compared to professional probes with a 99% accuracy level.
