We believe in controlling the quality of our products from their inception to delivery. For this reason, we manufacture all the products we bring to the market including, meters, electrodes, chemical reagents and buffer solutions. Our five manufacturing facilities are each specialized in a product family, ensuring stability and greater quality. Our engineers in manufacturing strive to achieve higher standards at all times, continuously investing in new manufacturing technology equipment as well as new manufacturing techniques. As a vertically integrated manufacturer, HANNA® does not subcontract any part of the manufacturing process, from plastic molding, to glass blowing and chemical bottling, to PCB and electronic assemblies.
