Oakton (WD-35624-22) pH Tester 2; +0.1 pH Accuracy
Oakton pH Tester 2 (WD-35624-22)
Waterproof floating pH meter with replaceable electrode and automatic temperature compensation for reliable testing in any water environment
Professional-grade pH testing that floats, not sinks
Floats on Water
Buoyant design prevents loss in tanks and ponds. IP67-rated waterproof and dustproof construction for field reliability.
Auto Temperature Compensation
Built-in ATC maintains ±0.1 pH accuracy across 0 to 50°C operating range, correcting for temperature variations automatically.
Three-Point Calibration
Push-button calibration at pH 4.0, 7.0, and 10.0 with auto buffer recognition. Microprocessor handles the setup work.
Replaceable Electrode
Single junction electrode replacement extends meter body life indefinitely. Replace only the electrode, reuse the tester body and electronics.
Wide Range Coverage
Measures -1.0 to 15.0 pH with 0.1 pH resolution. Hold function locks readings, auto-off conserves battery, error messages guide troubleshooting.

Replacement Schedule
pH Electrode Replacement
Replace single junction electrode when readings drift or calibration fails. Frequency depends on usage intensity and sample chemistry.
Battery Replacement
Replace three 1.5V batteries after approximately 24 hours of continuous operation. Auto-off feature extends battery life during intermittent use.
Calibration Check
Verify calibration weekly for critical applications. Recalibrate using pH 4.0, 7.0, and 10.0 buffer solutions when drift exceeds ±0.1 pH.
Lower Long-Term Cost
Replaceable electrode design means you only replace the sensor, not the entire meter body and electronics
Lab-Grade Accuracy
±0.1 pH precision with ATC meets professional testing standards for water treatment, aquaculture, and quality control
Field-Ready Design
Floats to prevent loss, IP67 waterproof rating, and hold function make this ideal for outdoor and industrial testing
Smart Calibration
Auto buffer recognition and error messages eliminate guesswork, while three-point calibration ensures accuracy across the full pH range
