HANNA has prided itself in being one of the world's leaders in innovation of analytical instrumentation. Headed by our team in Woonsocket, Rhode Island, HANNA's Research & Development teams constantly challenge themselves to improve on existing technology and to invent new testing techniques with the common goal to simplify analytical testing. Hanna was first to introduce to a pH electrode with a built in temperature sensor (HI1217S) which became world wide and commonly used throughout the market. The idea of waterproof portable instruments to be used in harsh environments also was launched by HANNA in 1990 (HI9025).
