Featuring a highly sensitive platinum band sensor and gel electrolyte, it utilizes a pinless, round stainless steel connector for foolproof installation. It instantly restores factory ORP accuracy to the Hanna HI98120 (ORP) and HI98121 (pH\/ORP Combo) pocket meters.\u003c\/p\u003e\n\u003cp\u003eInstantly restore your ability to track critical water sanitization with the \u003cstrong\u003eHanna HI73120 Spare ORP Electrode Cartridge\u003c\/strong\u003e. For swimming pool maintenance teams and industrial wastewater technicians across Pakistan, tracking Oxidation-Reduction Potential (ORP) is the only way to prove that chlorine or ozone is actively killing bacteria. Over time, heavy minerals and aggressive chemicals coat the platinum sensor on your pocket meter, causing the mV readings to become sluggish or freeze entirely.\u003c\/p\u003e\n\u003cp\u003eThe HI73120 is the ultimate cost-saving solution. Instead of discarding your rugged Hanna HI98120 or HI98121 tester, you simply twist out the old sensor and pop in this brand-new Platinum Band Cartridge. It features a heavy-duty Stainless Steel Round Connector, entirely eliminating the risk of bending delicate electrical pins during installation. Dual O-rings guarantee the meter remains 100% waterproof and buoyant. It is a 10-second upgrade that brings your meter back to laboratory-grade precision.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEquip your commercial facility via [\u003ca href=\"https:\/\/kamadi.pk\/collections\/lab-supplies\"\u003eLab Supplies\u003c\/a\u003e].\u003c\/li\u003e\n\u003cli\u003eShop premier analytical hardware under [\u003ca href=\"https:\/\/kamadi.pk\/collections\/analytical-instruments\"\u003eAnalytical Instruments\u003c\/a\u003e].\u003c\/li\u003e\n\u003cli\u003eCompare specific ORP replacement cartridges in [\u003ca href=\"https:\/\/kamadi.pk\/collections\/electrodes-probes\"\u003eElectrodes \u0026amp; Probes\u003c\/a\u003e].\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlatinum Band Sensor\u003c\/strong\u003e: The global standard for highly reactive, instant ORP (Redox) readings in swimming pools, cooling towers, and ETP neutralization tanks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePinless Cartridge Design\u003c\/strong\u003e: The stainless steel round connector ensures rapid, foolproof installation without breaking fragile components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstant Revitalization\u003c\/strong\u003e: Saves massive procurement budgets by reviving existing meters instead of buying entirely new hardware.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGuaranteed Compatibility\u003c\/strong\u003e: The exact replacement cartridge specifically engineered for the Hanna HI98120 (ORP Tester) and HI98121 (pH\/ORP Combo Tester).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQs):\u003c\/h3\u003e\n\u003ch3\u003eQ: What is the price of the Hanna HI73120 in Pakistan?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eA\u003c\/strong\u003e: Contact Kamadi.pk for formal corporate pricing.

The HI73120 is strictly an ORP (mV) sensor. If you plug it into an EC meter, it will not function. You must ensure your meter model specifically reads ORP.\u003c\/p\u003e\n\u003ch3\u003eQ: Do I need to calibrate the ORP?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eA\u003c\/strong\u003e: ORP sensors do not technically require the frequent calibration that pH sensors do, but you can verify its accuracy by dipping it into Hanna HI7021 (240 mV) ORP Test Solution to ensure the new platinum band is responding perfectly.\u003c\/p\u003e","brand":"Hanna","offers":[{"title":"Default Title","offer_id":48638728470785,"sku":"811410129","price":38000.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0731\/5659\/1873\/files\/hanna_hi73120_electrode.jpg?v=1778274077","url":"https:\/\/kamadi.pk\/products\/hanna-hi73120-spare-orp-electrode-cartridge-pocket-testers","provider":"Kamadi Pakistan","version":"1.0","type":"link"}
