Some water quality products, notably pH and ORP probes as well as calibration solutions, are sensitive to freezing temperatures. Instrumart recommends overnight shipping and is not responsible for damage due to freezing. Contact us for more information.

The Oakton Instruments pH Testers 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 the Oakton Instruments pH tester even in dirty or damp field conditions. Waterproof housing is also great for taking outdoor measurements. Oakton Instruments pH testers also float.

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

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