MULTIPARAMETER WATER QUALITY METER Rugged, waterproof and easy to use, the HI 9829 is the ideal meters for field measurements of lakes, rivers and seas. Both meters display 1 to 12 parameters simultaneously from up to 15 user selectable parameters. Combined with one of the HI 76x9829 series probes, the HI 9829 can measure water quality parameters such as pH, ORP, conductivity, turbidity, temperature, ions ions ammonium, nitrate, chloride (NH4+, NO3-—N or Cl-), dissolved oxygen concentration, resistivity, TDS, salinity, and seawater specific gravity. Atmospheric pressure is measured for DO compensation. This meter features a graphic, backlit LCD that scales digits to fit up to 12 parameters and allows full configuration of each parameter measured along with an on-screen graphing capability. HI 9829 incorporates comprehensive GLP features and the transferring of data via USB connection. The HI 98290’s HELP key displays context sensitive help. The alpha-numeric keypad offers a user friendly way to complete the input fields. Features: Field replaceable ISO 7027 compliant turbidity sensor Ammonium, chloride and nitrate ISE’s Logging from probe or meter Fully customizable instrument, probe, sensors and measurement specifications Display from 1 to 12 parameters with font dimension adjustment Field replaceable sensors pH/ORP or pH, four electrode EC and galvanic DO sensors Auto-recognition of all sensors Rugged probe with stainless steel tip has a diameter under 2” for wells and pipes Fast Tracker™—Tag I.D. System simplifies periodic monitoring Features a built-in barometer for DO compensation Quick or independent sensor calibration feature Measurement check eliminates erroneous readings Logged data can be displayed as graphs Graphic LCD with backlight USB for PC connectivity Good Laboratory Practice feature with last five calibrations recorded Meter accepts both alkaline and rechargeable batteries Waterproof protection for meter (IP67) and probes (IP 68) Specification: Range    pH/mV of pH input    0.00 to 14.00 pH/±600.0 mV ORP mV    ±2000.0 mV Ammonium- Nitrogen    0.02 to 200 ppm (as N) Chloride    0.6 to 200 ppm Nitrate-Nitrogen    0.62 to 200 ppm (as N) Conductivity    0 to 200 mS/cm (absolute EC up to 400 mS/cm) TDS    0 to 400000 mg/L or ppm (the maximum value depends on the TDS factor) Resistivity    0 to 999999 Ω•cm; 0 to 1000.0 kΩ•cm; 0 to 1.0000 MΩ•cm Salinity    0.00 to 70.00 PSU Seawater σ    0 to 50.0 st, s0, s15 Turbidity    0.0 to 99.9 FNU; 100 to 1000 FNU Dissolved Oxygen    0.0 to 500.0%; 0.00 to 50.00 ppm Atm.
