HI97101 Bromine, Free and Total Chlorine, Cyanuric Acid, Iron LR, Iodine and pH 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 10 Photometers 10.108 | www.hannainst.com portable
