High-Accuracy Dissolved Oxygen Meters for Education & Research
We provide Dissolved Oxygen Meters that empower educators, researchers, and students to investigate aquatic health with precision and confidence. Measuring dissolved oxygen (DO) is vital for assessing water quality in lakes, rivers, ponds, and other aquatic ecosystems. Our DO meters are built for the classroom, field, or lab—offering reliable results in real time. Whether you’re performing water sampling as part of a science curriculum or conducting long-term environmental studies, our instruments simplify complex testing procedures while delivering research-grade data. Based in Philadelphia, PA, we’ve become a trusted name in the education industry across North America. With a strong focus on technology innovation, product durability, and responsive customer service, we equip learning environments with tools that foster scientific exploration and environmental stewardship.
The Following are Our Advanced Offerings for Dissolved Oxygen Meters
In addition to offering products and systems developed by our own and other partners for Dissolved Oxygen Meters, we are proud to carry top-tier products and systems from our trusted partners, GAO Tek Inc. and GAO RFID Inc., delivering reliable, high-quality technologies, integration and services you can count on. When appropriate, we have provided links to relevant products and systems of GAO TEK Inc. and GAO RFID Inc.

Case Studies
California Public School District
A Southern California school district implemented Enviro Education Tools’ pH meters in over 40 middle school classrooms. The result: a 35% increase in student engagement during water chemistry lessons, and the integration of real-time fieldwork in school garden programs.
Community College in Ohio
An Ohio community college used our pH meters during environmental field labs near the Great Lakes. With Bluetooth data syncing, instructors easily tracked individual and group data, aligning with their course’s digital-first approach.
Canada Ontario STEM Academy
An independent STEM academy in Ontario integrated our meters into a watershed education module. Students used pH data to evaluate the impact of urban runoff on a local river, leading to a class-led sustainability project and local policy discussions.
