The waterproof Oakton PCTestr 35 and PTTestr 35 dual parameter testers offer the ability to take two important measurements in one instrument. The Oakton PCTestr 35 measures conductivity and pH, and the Oakton PTTestr 35 measures TDS and pH. Simply press a key to toggle between readings. These waterproof testers float so there is no need to worry about the tester sinking to the bottom of your tank or pond.

The Valox housing and stainless steel electrodes offer good chemical compatibility and durability. All waterproof Oakton PCTestr 35 and PTTestr 35 dual parameter testers have replaceable sensors. The meter bodies can be reused multiple times without losing waterproof or dustproof protection.

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.
