Product Code: HI73128 The Hanna HI73128 Electrode Removal Tool is a replacement tool designed to safely and easily remove replaceable electrode cartridges from select Hanna waterproof testers. With a simple twist of the tool, the electrode can be released from the tester and replaced with a new cartridge without replacing the complete instrument. The HI73128 is particularly useful for maintaining Hanna pocket testers with replaceable pH, ORP, conductivity, and TDS electrodes. Electrodes naturally wear or become contaminated over time, and the HI73128 makes electrode replacement a quick and straightforward process.To remove a compatible electrode cartridge, insert the HI73128 into the probe cavity and rotate it counterclockwise to release the electrode. Use the opposite side of the tool to pull the electrode cartridge out of the tester. A replacement electrode can then be installed by reversing the procedure.
