Hanna pH/ATC Portable Meter. The Hanna pHep4 waterproof tester is an advanced meter that has many features found in more expensive portable and benchtop meters. This ergonomic meter features automatic one or two point calibration to known buffer, automatic temperature compensation, battery percent level indicator at start up, and a stability indicator to alert the user when a stable reading has been obtained.

The large multi level LCD display that shows both pH and temperature simultaneously. The pHep4 tester also features a replaceable pH probe that has a unique extendable cloth junction to clear any clogging that occurs.

We recommend the electrode cleaning solution and the electrode storage solution to prolong the life of your electrode and keep it operating correctly. The cleaner will extend the life of your electrode & the storage solution is a must-have in keeping the electrode healthy.
