Utilizing an adaptation of the EPA Diazotization method, it accurately measures nitrite concentrations from 0.000 to 0.600 mg\/L (ppm) as NO_2-N. Featuring CAL Check™ performance validation and an IP67 casing, it is the standard diagnostic instrument for municipal water treatment plants and sensitive aquaculture environments.\u003c\/p\u003e\n\u003cp\u003eEnsure absolute public safety and marine health with the \u003cstrong\u003eHanna HI97707 Nitrite Low Range Photometer\u003c\/strong\u003e. In municipal drinking water, elevated nitrite levels are highly toxic, causing \"blue baby syndrome\" by restricting oxygen in the blood. Similarly, in commercial aquaculture and high-end aquariums across Pakistan, nitrite is lethal to fish even at microscopic levels. Municipal WASA authorities and fisheries must monitor these levels with flawless, legally verifiable precision.\u003c\/p\u003e\n\u003cp\u003eThe HI97707 is explicitly designed for this critical safety task. Operating on the globally recognized EPA Diazotization Method, it measures nitrite concentrations in the ultra-sensitive 0.000 to 0.600 mg\/L (ppm) range with a staggering 0.001 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 due to battery drain. Fully IP67 Waterproof, it is built to survive daily field testing at remote municipal tube-wells and fish hatcheries.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBrowse heavy industrial compliance gear in [\u003ca href=\"https:\/\/kamadi.pk\/collections\/lab-supplies\"\u003eLab Supplies\u003c\/a\u003e].\u003c\/li\u003e\n\u003cli\u003eShop essential plant maintenance tools under [\u003ca href=\"https:\/\/kamadi.pk\/collections\/analytical-instruments\"\u003eAnalytical Instruments\u003c\/a\u003e].\u003c\/li\u003e\n\u003cli\u003eCompare specific ion photometers in our [\u003ca href=\"https:\/\/kamadi.pk\/collections\/photometers-colorimeters\"\u003ePhotometers \u0026amp; Colorimeters\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\u003eEPA Compliance\u003c\/strong\u003e: Utilizes the exact chemical methodology required by international Environmental Protection Agencies for isolating toxic nitrite.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-Low Sensitivity\u003c\/strong\u003e: The 0.001 mg\/L resolution provides the absolute earliest warning of biological filter failure in commercial aquaculture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCAL Check™ Verification\u003c\/strong\u003e: Instantly proves the meter is functioning flawlessly using Hanna's certified, NIST-traceable optical standards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePositive-Locking Cuvette\u003c\/strong\u003e: Ensures the glass vial locks into the exact same position every time, preventing optical alignment errors.\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 HI97707 in Pakistan?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eA\u003c\/strong\u003e: Check Kamadi.pk for competitive B2B rates.
