AquaMetrix has been manufacturing state-of-the-art, durable and cost effective water quality analysis equipment for over 50 years. Its roots date back to the differential pH/ORP sensor that was developed for the Canadian market from the original Great Lakes patent. Over the years the company has added sensors for pH, ORP, conductivity, dissolved oxygen, and flow. Two generations of controllers cemented the AquaMetrix reputation as the manufacturer of instrumentation for the harshest of environments.
