When Hanna introduced its first version of the pHep (pH electronic paper) in 1986, it immediately revolutionized the standard in pH measurement. pHep’s ease-of-use in combination with its affordability made it possible for non-technical and technical personnel alike to measure pH on the spot, accurately and inexpensively throughout a variety of industries. Since its introduction, over 1 million pHeps have gone to satisfied customers around the world.

We at Hanna have always valued the comments and suggestions coming from our customers. For this series, we have included all of the features you have asked for and more!
