Such as cola drinks to enhance flavour and tartness, antifreeze as a pH buffer, and French fries to delaying darkening of the cut potatoes. They are also extensively used in detergents and cleaning fluids because of their ability to soften water and remove soil deposits.\u003c\/p\u003e \u003cp\u003ePhosphate is essential for the growth and development of plant roots, stems, flowers and seeds, hence why it is one of the most commonly added to fertilisers. However, high concentrations of phosphates in agricultural runoff 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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003e0.00 to 2.50 mg\/L (as PO43-)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e0.01 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy @25°C\u003c\/td\u003e\n\u003ctd\u003e±0.04 mg\/L ±4% of reading at 25°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethod\u003c\/td\u003e\n\u003ctd\u003eAdaptation of the Ascorbic Acid Method\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Source\u003c\/td\u003e\n\u003ctd\u003elight emitting diode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBandpass filter\u003c\/td\u003e\n\u003ctd\u003e610nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBandpass filter bandwidth\u003c\/td\u003e\n\u003ctd\u003e8nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBandpass filter wavelength accuracy\u003c\/td\u003e\n\u003ctd\u003e±1.0nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Detector\u003c\/td\u003e\n\u003ctd\u003eSilicon photocell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCuvette type\u003c\/td\u003e\n\u003ctd\u003eRound 24.6mm diameter (22mm inside)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAuto logging\u003c\/td\u003e\n\u003ctd\u003e50 readings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003e128 x 64 pixel B\/W LCD with backlight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAuto-off\u003c\/td\u003e\n\u003ctd\u003eAfter 15 minutes of inactivity (30 minutes before a READ measurement)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery type\/life\u003c\/td\u003e\n\u003ctd\u003eAlkaline 1.5 V AA (3)\/ \u0026gt;800 measurements (without backlight)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnvironment\u003c\/td\u003e\n\u003ctd\u003e0 to 50°C; 0 to 100% RH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e142.5 x 102.5 x 50.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e380g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrdering information\u003c\/td\u003e\n\u003ctd\u003eHI-97713 is supplied with sample cuvettes (2), sample caps (2), plastic stoppers (2), 1.5V AA batteries (3), instrument quality certificate and instruction manual.
