Signi¡cance of Use In some areas around the world, bromine is replacing other more common disinfectants, such as chlorine. Due to its stability at higher temperatures and higher pH levels, bromine is most often used in sanitization of pools and spas, and cooling towers.

Reagents sold separately Reagents and Standards HI97716 HI97716-11 CAL Check standard cuvettes for bromine HI93716-01 bromine reagents for 100 tests HI93716-03 bromine reagents for 300 tests HI97716 Bromine 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 See page 10.128 for standard reagents; see page 10.129 for CAL Check kits; see page 10.66 for general accessories 10 Photometers 10.71 www.hannainst.com | portable
