Manufacturer Info

Hanna Instruments USA Aquarium Supplies
Hanna Instruments is a leading manufacturer of analytical aquarium instrumentation. They were founded in 1978 and are headquartered in Woonsocket, Rhode Island. When Hanna introduced 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. Hanna employees are constantly challenging 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. Hanna also believes in controlling the quality of their products from inception to delivery so they manufacture everything themselves, from meters and electrodes to chemical reagents and buffer solutions.

easy to replace

My Hanna Combo meter was taking a long time to read the PH values, and was constantly drifting. (18Months old). after replacing the electrode it calibrated quickly and reads reads my ph levels very quick without any drifting. plus the best price and service was found at the website and same day i ordered my parts, was the same day the parts were shipped by UPS.(UPS is another story)
