Freshwater Tinykit

Our smallest testkit, the Tiny Testkit is designed for young learners with no previous water testing experience and for those wanting an introduction to water testing. Tiny, lightweight and convenient for quick sampling. This kit can be used by 1 to 2 kids at a time. You can also buy a 10 pack here.

This campaign is organized as part of Take Me Outside Day and #NatureForAll! We want to thank NSERC for making programs like this possible.
