Utilizing the EPA-approved DPD colorimetric method, it delivers precise readings from 0.00 to 5.00 mg\/L (ppm). Equipped with a proprietary LED optical system, an 8 nm narrowband interference filter, and CAL Check™ validation, it is the standard QA tool for verifying municipal drinking water safety and food processing sanitation.\u003c\/p\u003e\n\u003cp\u003eGuarantee the biological safety of your water supply with the \u003cstrong\u003eHanna HI97701 Free Chlorine Photometer\u003c\/strong\u003e. In commercial food processing, pharmaceutical manufacturing, and municipal drinking water plants across Pakistan, chlorine is the primary line of defense against waterborne bacteria. However, you must measure Free Chlorine—the active, unused chlorine that is actually available to kill pathogens.\u003c\/p\u003e\n\u003cp\u003eThe HI97701 is explicitly designed to isolate and measure this critical parameter. Operating on the recognized DPD Method (EPA 330.5), it measures Free Chlorine concentrations across the standard 0.00 to 5.00 mg\/L (ppm) range with a highly precise 0.01 mg\/L resolution. The meter features a Reference Detector that constantly modulates the voltage to the internal LED, ensuring that the light output never drifts. Fully IP67 Waterproof and featuring the CAL Check™ System, it is the ultimate compliance tool for health inspectors.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFind specialized industrial testing gear in [\u003ca href=\"https:\/\/kamadi.pk\/collections\/lab-supplies\"\u003eLab Supplies\u003c\/a\u003e].\u003c\/li\u003e\n\u003cli\u003eShop advanced chemical analytics under [\u003ca href=\"https:\/\/kamadi.pk\/collections\/analytical-instruments\"\u003eAnalytical Instruments\u003c\/a\u003e].\u003c\/li\u003e\n\u003cli\u003eCompare dedicated oxidizer photometers in [\u003ca href=\"https:\/\/kamadi.pk\/collections\/photometers-colorimeters\"\u003ePhotometers \u0026amp; Colorimeters\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\u003eFree Chlorine Specific\u003c\/strong\u003e: The mandatory tool for ensuring your water actually has the active chemical required to neutralize harmful bacteria.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces Subjective Color Charts\u003c\/strong\u003e: Eliminates the human error associated with trying to guess the shade of pink on cheap chemical testing blocks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCAL Check™ Diagnostics\u003c\/strong\u003e: Automatically ensures the LED and lens are performing flawlessly, providing verifiable proof for health inspectors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in Reaction Timer\u003c\/strong\u003e: Ensures the DPD chemical reaction is 100% finished before the measurement is taken.\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 HI97701 in Pakistan?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eA\u003c\/strong\u003e: Contact Kamadi.pk for formal corporate pricing.
