Freshwater Tinykit 10-pack


Are you working with a group of students or volunteers? Our smallest testkit, the Tiny Testkit, is perfect for you!

Our pack of 10 Tiny Testkits is an affordable option for those working with 10-20 kids or for groups wanting to try water testing for the first time. You can also buy a single kit here.

The answer depends on how often you use your kit! While our official schedule involves testing once per month, some of our testers decide to go out weekly. If you are going to test during our official testing weekends, the Freshwater and Compact kits will last well over a year. If you are going out to test more frequently, we recommend that you use some of the more expensive tests less often, such as the dissolved oxygen kit.
