HI97718 Iodine Portable Photometer • Advanced LED optical system · Innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette. · LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce little heat, which could otherwise affect electronic stability. • CAL Check™ · Validate instrument performance at any time using CAL Check cuvettes made with NIST traceable standards. The CAL Check screen guides the user step-by-step through the validation process and user calibration. • On-screen tutorial mode with animations · Guides users step-by-step through the measurement process • Waterproof and floating IP67 case • Unit of measure is displayed along with reading • Built-in timer · Built-in reaction timer that ensures consistency between tests. • Error messages on display · Alerts to problems including no cap, high zero, and standard too low • GLP data · Displays the last calibration date. • Auto logging • Battery status indicator • Auto-shut off Signi¡cance of Use The disinfectant properties of iodine have led to its use as an alternative to chlorine and bromine. Unlike chlorinated pools, water treated with iodine decreases eye irritation among swimmers and provides a level of disinfection more stable to adverse conditions. However, its toxic and corrosive properties, along with the di¤culties of dissolving it in water, have limited its widespread acceptance. One of the most common applications of iodine is in poultry industry process water.
