Designed to instantly verify the health and accuracy of ORP electrodes, it provides a stable, highly specific 470 mV reference point (@25°C). It is a mandatory diagnostic liquid for commercial pool operators and industrial wastewater technicians.\u003c\/p\u003e\n\u003cp\u003eStop guessing if your ORP sensor is actually working with the \u003cstrong\u003eHanna HI7022L 470 mV ORP Test Solution\u003c\/strong\u003e. In commercial swimming pools or chemical plating baths across Pakistan, Oxidation-Reduction Potential (ORP) is the ultimate metric for sanitization strength. However, ORP electrodes are notorious for becoming coated in invisible oils or microscopic scale, which dulls the platinum sensor and causes sluggish, inaccurate readings.\u003c\/p\u003e\n\u003cp\u003eUnlike pH meters, you generally do not calibrate an ORP meter; instead, you test the probe's health. By dipping your electrode into a beaker of HI7022L, the meter should read exactly 470 mV (@25°C). If your meter reads significantly higher or lower, you instantly know the platinum tip is dirty, oxidized, or physically depleted. Packaged in a 500 mL light-blocking bottle, this air-tight solution ensures you never accidentally under-dose chlorine or ozone due to a faulty sensor.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRestock your plant maintenance supplies in [\u003ca href=\"https:\/\/kamadi.pk\/collections\/lab-supplies\"\u003eLab Supplies\u003c\/a\u003e].\u003c\/li\u003e\n\u003cli\u003eShop essential probe care fluids under [\u003ca href=\"https:\/\/kamadi.pk\/collections\/lab-chemicals\"\u003eLab Chemicals\u003c\/a\u003e].\u003c\/li\u003e\n\u003cli\u003eCompare specific millivolt solutions in our [\u003ca href=\"https:\/\/kamadi.pk\/collections\/calibration-standards-buffers\"\u003eCalibration Standards \u0026amp; Buffers\u003c\/a\u003e] collection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstant Health Check\u003c\/strong\u003e: The only definitive way to prove whether a sluggish ORP reading is caused by the water chemistry or a broken electrode.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHighly Stable 470 mV\u003c\/strong\u003e: Formulated with lab-grade chemicals to provide a rock-solid electrical reference point.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight-Block Bottle\u003c\/strong\u003e: The FDA-compliant, opaque 500 mL bottle prevents UV light degradation, massively extending the solution's shelf life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLot Traceability\u003c\/strong\u003e: Features a clearly marked lot number and expiration date for seamless GLP record keeping.\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 HI7022L in Pakistan?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eA\u003c\/strong\u003e: Visit Kamadi.pk for current pricing.

First, try cleaning the platinum tip of the ORP probe with a mild abrasive or specialized cleaning solution, then re-test it in the HI7022L. If it still fails to reach 470 mV, the probe is likely depleted and must be replaced.\u003c\/p\u003e\n\u003ch3\u003eQ: Can I dip my probe directly into the bottle?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eA\u003c\/strong\u003e: No. Always pour a small amount of the solution into a clean beaker for testing, and discard it after use. Dipping the probe directly into the bottle will contaminate the entire 500 mL supply.\u003c\/p\u003e","brand":"Hanna","offers":[{"title":"Default Title","offer_id":45944236769537,"sku":"811410015","price":12800.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0731\/5659\/1873\/files\/hanna_7022l.jpg?v=1765219311","url":"https:\/\/kamadi.pk\/products\/hanna-hi7022l-470-mv-orp-test-solution-500ml","provider":"Kamadi Pakistan","version":"1.0","type":"link"}
