Never watch a tester sink to the bottom of your tank or pond! These waterproof testers float, so there’s no need to worry. Valox® housing and stainless steel electrodes offer good chemical compatibility and durability. All waterproof meters have replaceable sensors. Reuse the meter body many times without losing waterproof and dustproof protection.

Use the WD-35662-35 for either cup-style or dip-style measurements. For cup style, pour a small amount of your sample directly into the sensor cup until it overflows; for dip style, simply immerse tester tip into sample. Note: Before measuring, calibrate tester as either cup style or dip style (depending on intended method of use).
