Hanna Instruments

Through the years, the philosophy of the Nardo family has always been to be able to supply customers around the world with practical affordable solutions for their testing needs. When Hanna introduced the pHep (pH Electronic Paper) in 1986 it literally revolutionized the world of testing by allowing millions of people in various industries to test for pH in a simple, accurate and affordable way. This winning philosophy is still strongly embedded in HANNA.® In 2005, when we introduced the world's first single parameter series of automatic titrators dedicated to food analysis, we put thousands of users around the world in the position to perform their own analytical tests in house, and to improve the quality of their product. The driving philosophy that has been a trademark of HANNA has translated into a top class world wide organization with over 1,000 employees, including Sales and Technical Support, Research & Development and Manufacturing centers in 31 different countries

    The Hanna Marine Alkalinity (dKH) Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine absorbance and ion concentration. This level of instrumentation also offers greater resolution and accuracy, but can cost hundreds of dollars. The Hanna Marine Alkalinity Checker® uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.
