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 Testrs have replaceable sensors. Reuse the meter body many times without losing waterproof and dustproof protection.
