HI97737 Silver 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 At times, silver is used in the disinfection of pools and spas, as well as in water ¡lters. As small quantities of silver acts as a bacteriostatic agent preventing the growth of bacteria. The presence of silver in water is also indicative of pollution, mainly from ¡lm manufacturers, ¡lm processors, and surface ¡nishers. Silver levels are closely monitored since its presence in drinking water can cause discoloration of the skin, eyes, and mucous membranes.
