Hanna HI73311 Spare EC/TDS Electrode Cartridge for Pocket Testers

The Hanna HI73311 is a proprietary, easy-fit replacement Electrical Conductivity (EC) and Total Dissolved Solids (TDS) electrode cartridge. Designed exclusively for Hanna's flagship DiST® waterproof pocket testers, it features highly durable graphite sensors that resist oxidation and scaling. Utilizing a pinless, round stainless steel connector, it restores instant factory accuracy to the HI98311 (DiST 5) and HI98312 (DiST 6) meters.

Never let a fouled sensor halt your daily water auditing. The Hanna HI73311 Spare EC/TDS Electrode Cartridge is the ultimate lifesaver for commercial Reverse Osmosis (RO) technicians and hydroponic farmers across Pakistan. Over time, dipping your meter into heavy agricultural fertilizers or hard groundwater coats the sensors with calcium and mineral scale, causing the conductivity readings to drift or freeze entirely.

Instead of discarding your legendary Hanna DiST® tester, simply replace the engine. The HI73311 is an ingenious Cartridge-Style Sensor that snaps perfectly into the bottom of your existing meter. It utilizes Graphite Sensors rather than stainless steel, completely preventing the oxidation and polarization errors caused by aggressive chemical fertilizers. Featuring a rugged Stainless Steel Round Connector, there are no delicate electrical pins to snap during installation. Dual O-rings guarantee your meter remains 100% waterproof, restoring laboratory-grade precision in 10 seconds.

• Pinless Cartridge Design: The stainless steel round connector ensures rapid, foolproof installation without breaking fragile components.
• Instant Revitalization: Saves thousands of rupees by allowing you to replace only the exhausted sensor rather than purchasing an entirely new waterproof meter.
• Guaranteed Compatibility: The exact replacement cartridge specifically engineered for the Hanna HI98311 (DiST 5) and HI98312 (DiST 6).

Frequently Asked Questions (FAQs):

Q: What is the price of the Hanna HI73311 in Pakistan?

A: Visit Kamadi.pk for current pricing. We carry massive stock of Hanna replacement cartridges to ensure your field technicians are never without a working meter.

Q: Will this fit my HI98129 Combo meter?

A: No. The HI98129 Combo requires the HI73127 pH cartridge. The HI73311 is strictly for the DiST 5 and DiST 6 EC/TDS-only testers.

Q: Do I need to recalibrate after replacing the cartridge?

A: Yes. You must dip the new sensor into a standard calibration solution (like 1413 µS/cm or 1382 ppm) to sync the fresh graphite to the meter's microchip.
