Everything students need to know about environmental water parameters - In One Backpack!

HANNA® is now offering a new series of test kits specifically designed for Educators and Environmental Science students. These portable kits contain well constructed lessons and activities, and will allow the teacher to get the most out of their classroom time.

Backpack Lab™ is designed with all the necessary components in one place, reducing the chance of misplacing an item. This durable backpack is ideal to take to the field for on-site measurements.

The components are tied together by a comprehensive teachers manual that includes information about each parameter, classroom activities designed to introduce students to each parameter, and detailed field testing procedures. HANNA®'s parameter test kits and pocket testers, provide teachers with a valuable tool in helping students assess the water quality of streams, rivers and lakes.
