HI97713 • HI97717 Phosphate, Low and High Range Portable Photometers • 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 Specifications HI97713 Phosphate, LR HI97717 Phosphate, HR Measurement Range 0.00 to 2.50 mg/L (as PO¹· - ) 0.0 to 30.0 mg/L (ppm) (as PO¹· - ) Resolution 0.01 mg/L 0.1 mg/L Accuracy @25°C (77°F) ±0.04 mg/L ±4% of reading at 25°C ±1.0 mg/L ±4% of reading Method Adaptation of the Ascorbic Acid method Amino Acid Method, adapted from Standard Method for the Examination of Water and Wastewater Measurement System Light Source light emitting diode Bandpass filter 610 nm 525 nm Bandpass filter bandwidth 8 nm Bandpass filter wavelength accuracy ±1.0 nm Light Detector silicon photocell Cuvette type round 24.6 mm diameter (22 mm inside) Additional Specifications Auto logging 50 readings Display 128 x 64 pixel B/W LCD with backlight Auto-off after 15 minutes of inactivity (30 minutes before a READ measurement) Battery type / Life alkaline 1.5 V AA (3) / > 800 measurements (without backlight) Environment 0 to 50°C (32 to 122°F); 0 to 100% RH, non-serviceable Dimensions 142.5 x 102.5 x 50.5 mm (5.6 x 4.0 x 2.0") Weight 380 g (13.4 oz.)

Such as cola drinks to enhance avor and tartness, antifreeze as a pH buer, and french fries to delaying darkening of the cut potatoes. They are also extensively used in detergents and cleaning uids because of their ability to soften water and remove soil deposits. Phosphate is essential for the growth and development of plant roots, stems, owers and seeds, hence why it is one of the most commonly added to fertilizers. However, high concentrations of phosphates in agricultural runo can cause environmental pollution, as they are a primary cause of eutrophication. Local laws govern the use of phosphates and the discharge levels into streams and waterways..
