The waterproof Oakton EcoTestr pH 2 tester is economical and easy to use. With its crystal clear, ergonomically designed display, the Oakton EcoTestr pH 2 tester makes it easy to view measurements at a glance. Each rugged pH 2 tester has waterproof and dustproof housing for use in dirty and damp field conditions. Simply dip and read — the orientation of the display means there's no need to turn your head or tilt the tester.

The Oakton EcoTestr pH 2 tester features a single-junction electrode that is well-suited for general purpose applications, using a recessed bulb with bulb guard which protects against breakage. You can also have up to three point calibration with auto-buffer recognition for quick calibrations. Automatic temperature compensation is another feature of the Oakton EcoTestr pH 2 tester for accurate readings under changing conditions. The hold function locks in measured value and auto-off function preserves batteries.

pH meters require regular calibration to perform at their optimal level. We strongly suggest purchasing calibration solutions. We offer both calibration kits and individual solutions to meet your needs.
