Hanna HI73127 Spare pH Electrode Cartridge for Pocket Testers

The Hanna HI73127 is a proprietary, easy-fit replacement pH electrode cartridge designed exclusively for Hanna's flagship waterproof pocket testers. Featuring a robust spherical glass tip, a cloth junction, and gel electrolyte, it utilizes a round stainless steel connector that completely eliminates the risk of bending or breaking delicate pins. It restores factory accuracy to the pHep®4, pHep®5, and the Combo HI98129/HI98130 series meters.

Never throw away a perfectly good pocket meter again! The Hanna HI73127 Spare pH Electrode Cartridge allows you to instantly revive your favorite field tester. In commercial hydroponics, municipal water auditing, and general field QA across Pakistan, the Hanna Combo testers (like the HI98129) are legendary for their durability. However, the sensing glass on any pH meter will eventually age, become sluggish, or get scratched.

Instead of buying a brand-new $150 meter, you simply replace the "engine." The HI73127 is an ingenious Cartridge-Style Sensor that snaps perfectly into the bottom of your existing Hanna tester. It features a rugged Stainless Steel Round Connector, meaning there are absolutely no delicate metal pins to align or accidentally snap off during installation. Equipped with dual O-rings to maintain the meter's 100% waterproof seal and a Renewable Cloth Junction, it instantly restores your pocket tester to brand-new, factory-calibrated precision.

Q: Do I need a special tool to remove the old probe?

A: You can pull it out by hand, but it is highly recommended to use the little black plastic removal tool (HI73128) that originally came in the box with your tester to easily twist the cartridge out.
