TECHNOLOGY       For three decades 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 & Developement teams constantly challenge themselves to improve on existing technology and to invent new testing techniques with the common goal to simplify analytical testing. This applies not only to instrumentation, but also to sensors development, reagents and chemicals.
