Superior Analytical Instruments (SAI) is a sales group that brings decades of experience in measurement and control of liquids and gasses to the upper mid-west region of the United States. We focus on providing the best solution for our customer’s application, not just selling a product. With over 20 years’ experience in the science of water treatment, measurement and practical application principals, SAI will help you solve your problem in the best way possible. Over the years we have seen many installations where a product was sold, not because the technology was the best in that application, but because it was the only technology the sales channel possessed. This often leads to performance issues, and premature failure. SAI's line card is extensive, but our network into the industry is far greater. If your process is bio-tech, pharmaceutical, environmental monitoring, pulp and paper, food and beverage, or water/wastewater, SAI can help you make the measurements and get it under control.
