Quality control 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 buer solutions. Each of our manufacturing facilities is specialized in a product family to ensure stability and greater quality. Our engineers in manufacturing strive to achieve higher standards at all times, continuously investing in new manufacturing equipment and 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, Hanna controls the manufacturing process in-house. All Hanna products are in compliance with international standards and our production facilities are ISO 9001 :2015 certi ed. Casing, injection, and rubber molding Hanna designs and manufactures all of our instrument casings, custom cases and inserts, solution and reagent bottles and rubberized shockproof boots. Electronics Our electronics department mounts and connects the electronic components onto our custom circuit boards. The boards are then tested and installed into our instruments. Glass blowing Our glass blowing department combines artistry and science to create our electrodes. Glass is heated and shaped within strict tolerances by hand in both of our facilities in Nusfalau, Romania and Rhode Island, USA. Electrode assembly Our glass blowing, injection molding and electronics department work together to supply our electrode assembly department with the materials they need to build Hanna electrodes. Labels and keypads All of the masks, labels and pad printing for our instruments and solution bottles is designed, printed, and die-cut in-house. Assembly Our assembly department nalizes the production of the instrument by putting all the components together to form a working instrument. This includes LCD’s, probes, buttons. Solutions Our solutions are formulated and mixed on premises and are prepared to precise formulas and standardized with a pH electrode and meter calibrated to NIST standards. Reagents Powder and liquid reagents are carefully formulated and lled to ensure maximum precision. Packaging Hanna produces the packaging for all product lines. The in-house control of all research, design and production steps provides continual quality control at all phases to assure the highest level of quality. Manuals and literature Our manuals and quick start guides are printed on our Heidelberg press as well as much of our lea¬ets, ¬yers, posters and catalogs. Final quality check After continuous validation and testing, Hanna products undergo a nal quality check before they are packaged and released to consumers.
