The name 'Phep' was given to one of our very first pocket pH testers when we first introduced pocket pH to the world market.

Today the Hanna HI 98107 (Phep), which is the result of over two decades of research and manufacturing experience, is the updated version.

The redesigned Phep features a rugged and ergonomically enhanced casing that fits comfortably in your hand and a larger LCD which makes it easier to read at any angle. With the latest innovation of a non-clogging fiber junction the new Phep meters last much longer. Simply pull out 1-2 mm (1/8") of the junction fiber to completely renew the junction.

Today it is still an easy to use pocket pH tester which provides digital readout of pH.

Simply dip the tester into the solution you want to measure, and read the pH to 0.1 resolution on the digital display.
