McNab designs and manufactures water quality control systems and instrumentation for the chemical and petrochemical processing, food and beverage, water quality, and marine industries to meet both North American and European standards. Our commercial application products have been used world wide since 1909.

It is not only the product that we sell, but also the service and support that makes McNab stand apart. Each system that our team of engineers, scientists, and executives creates is a result of extensive customer participation, as well as thorough research and development. We offer a full maintenance service contract on every system we provide. Our on-site laboratory is equipped with modern instrumentation for analysis and testing, as well as a DE (diatomaceous earth) pilot plant for equipment evaluation.

It is our goal to provide a product custom tailored to each customer's need, as well as creating a service program that protects and enhances your investment. From water conductivity meter equipment to reverse osmosis water purifier units, we can provide you with the custom water system solutions your business needs.

McNab also manufactures Jacoby-Tarbox optical and turbidity equipment. Our water quality monitoring equipment (linear and non-linear units) is available in six ranges.
