Environmental Test Kits

Backpack Lab designed for educators and environmental science students, containing lessons, activities, and test kits that relate to important parameters evaluated in soil quality. 

Use our simple handheld colorimeter to get higher accuracy water testing results. Forget about the struggle of matching your sample to a color chart, our total chlorine colorimeter eliminates the struggle and provides you a digital total chlorine result directly. Our ammonia colorimeter brings you more precise technology than your typical chemical test kit giving you accurate and consistent results.

These reagents are the replacement reagents for the total chlorine checker® HC. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.

The replacement reagents for the iron tester sold seperatly. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.
