It precisely heats up to 25 standard 16mm vials simultaneously to exactly 150°C (or 105°C). Featuring dual independent temperature sensors, an integrated countdown timer, and a protective safety shield, it is the absolute mandatory counterpart to any COD photometer for industrial wastewater compliance.\u003c\/p\u003e\n\u003cp\u003eYou cannot perform a Chemical Oxygen Demand test without the \u003cstrong\u003eHanna HI839800 COD Test Tube Heater (Thermo-Reactor)\u003c\/strong\u003e. Many procurement officers in Pakistan mistakenly buy a COD Photometer, only to realize the photometer cannot process raw samples. To measure COD, the organic matter in the wastewater must be chemically broken down (digested) using highly reactive sulfuric acid inside a sealed vial, baked at exactly 150°C for two hours.\u003c\/p\u003e\n\u003cp\u003eThe HI839800 is the heavy-duty engine that drives your entire ETP laboratory. Built to accommodate 25 standard 16mm vials simultaneously, it allows for massive batch processing of factory effluent. Because boiling acid in sealed glass vials is inherently dangerous, Hanna engineered this reactor with uncompromising safety. It features a heavy-duty Transparent Safety Shield, a thermal fuse to prevent overheating, and a massive aluminum block for perfectly uniform heat distribution across all 25 vials.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEquip your commercial laboratory via [\u003ca href=\"https:\/\/kamadi.pk\/collections\/lab-supplies\"\u003eLab Supplies\u003c\/a\u003e].\u003c\/li\u003e\n\u003cli\u003eShop essential sample preparation gear under [\u003ca href=\"https:\/\/kamadi.pk\/collections\/analytical-instruments\"\u003eAnalytical Instruments\u003c\/a\u003e].\u003c\/li\u003e\n\u003cli\u003eView the mandatory digestion hardware in our [\u003ca href=\"https:\/\/kamadi.pk\/collections\/bod-cod-meters\"\u003eBOD\/COD Meters\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\u003eThe Mandatory First Step\u003c\/strong\u003e: Photometers only read the vial; this reactor performs the chemical digestion required to make the reading possible.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Temperature Profiles\u003c\/strong\u003e: Pre-programmed to hold a rock-solid 150°C for COD tests, and 105°C for Total Nitrogen and Total Phosphorus digestion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMassive Capacity (25 Vials)\u003c\/strong\u003e: Allows industrial ETP managers to process an entire day's worth of plant effluent samples in a single 2-hour batch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Safety Shield\u003c\/strong\u003e: A heavy-duty polycarbonate drop-down shield protects laboratory technicians from the severe hazard of pressurized glass vial ruptures.\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 HI839800 in Pakistan?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eA\u003c\/strong\u003e: Check Kamadi.pk for competitive B2B rates.
