81.3 GENERAL DESCRIPTIONHI9828 is a multiparameter system that monitors up to 13 different water qual-ity parameters (6 measured, 7 calculated).The microprocessor based multisensor probe allows to measure all the param-eters necessary to evaluate the water quality, as dissolved oxygen saturation per-centage, conductivity, seawater specific gravity and other parameters that en-sure life in water as pH and temperature. The same probe can be used withdifferent meters without needing any recalibration.HI9828 is also provided with a built-in 12 channel GPS receiver and antenna,that guarantee a position accuracy of 10 m (30 ft).Measurements from specific locations are tracked with detailed coordinate in-formation that can be viewed immediately on the display.GPS information can be transferred to a PC using HANNA’s HI929828 soft-ware. GPS information can also be viewed using a GPS mapping software suchas Google™ Maps. Clicking on visited locations using a mapping software suchas Google™ Maps displays measurement information.For measuring points within a 10 meter range or where GPS signal is not avail-able, HI9828’s Fast Tracker™ is invaluable for associating measurements withtheir locations. HANNA’s exclusive Fast Tracker™—T.I.S. (Tag ID System) moni-tors and records data using iButton®s that can be installed at any number ofsampling sites.HI9828 features a graphic, backlit display that automatically sizes the digits tofit the screen and allows full configuration of each parameter measured alongwith on-screen graphing capability.Designed for outdoor environments, waterproof, resistant and easy to use, HI9828is the ideal solution for field measurements of lakes, rivers and sea.The meter meets IP67 standards (30 minutes immersion under 1 m of water);the multi sensor probe can be left underwater (IP68 standard).The setting menu can be protected by password to avoid not authorized modifi-cations and the help function is always available to explain the selected function,operation or message.GOOGLE™ is a registered trademark of Google, Inc.
