In 1986 Hanna Instruments revolutionized the way pH can be measured with the introduction of the pHep® (pH electronic paper). This tester brought the electronic pH measurement to the masses. It allowed farmers, students, and many other users access to a pH meter that was simple to use and very accurate. The meter was also very affordable with a price point less than $50.00.
Since the introduction of the pHep, Hanna Instruments has been at the forefront of innovating the tester technology. Our innovations include the first tester with a replaceable pH electrode, the first combination testers that can measure multiple parameters, the first with a large multi-level LCD that shows both pH and temperature readings, and now to an extensive line of application specific testers that are optimally designed for difficult samples including cheese, meat, bread, wine and beer, to name a few.
