Oakton pHTestrs feature unique double junction electrode design and increased reference gel volume to allow for significantly longer electrode life, especially in harsh applications.

The waterproof and dustproof (IP67 rated) housing maintains the integrity of Oakton pHTestrs even in dirty or damp field conditions. Waterproof housing is also great for taking outdoor measurements. Oakton pHTestrs also float.

The compact size of Oakton pHTestrs makes it easy to take these testers anywhere, and the double junction electrode will keep working even where pollutants cause problems for other meters.

Oakton pHTestrs also features replaceable electrodes, which makes it possible to reuse the same meter body. Other features of Oakton pHTestrs include push-button calibration with auto-buffer recognition, automatic temperature compensation with self-diagnostic error messages, hold function, and auto-off function.
