Our presale is back: 15% off for the 2026 testing season!
It’s that time of the year again! Our 2026 presale is now live! It may still be fall, but it’s never too early to think ahead to next year’s water testing season! Spring is a busy time at the Water Rangers warehouse, and by taking advantage of our presale, you’re helping us stock up and get ready to assemble all the kits needed for groups across the globe.
Plus, you can try out some of our newest tools, like our E. coli Testkit, designed to help community scientists get quick results for E. coli monitoring.
