Hanna Instruments HI 9828/10 Multiparameter Water Quality Meter with 10m pH/EC/DO Probe and Kit Review
The HI 9828/10 is a multi-parameter meter capable of measuring 12 different water quality parameters including pH, electro-conductivity (EC), Total Dissolved Solids (TDS), Oxidation Reduction Potential (ORP), dissolved oxygen (DO), atmospheric pressure, resistivity, salinity, seawater specific gravity, and temperature.
The HI meter is capable of holding up to 60,000 samples with 12 measurements each and has graphing capabilities. The meter has a calibration check feature that verifies probe functionality, and a Good Laboratory Practices (GLP) function that recalls the last five calibrations. It also features a backlit LCD to reduce glare, auto-recognition of the attached probe, and a USB connection for downloading data to Windows. The meter can operate on alkaline or rechargeable batteries and also includes a 12VDC power adapter for periods of prolonged use.
With the Hanna Instruments Fast Tracker Tag Identification System and internal GPS, test logging is simplified by placing iButton tags containing a stainless steel-encased computer chip with a unique identification code at various sampling sites. iButton tags can be screwed into place at various sites, and read by touching the meter to the tag to record location, date, time and water quality measurements at tagged locations.
The HI9828/10 tester functions and provides automatic temperature compensation (ATC) in temperatures of -5 to 55 degrees C (23 to 131 degrees F) (accuracy + or - 0.15 degrees C; + or - 0.27 degrees F; + or - 0.15K), and has a range of pH 0.0 to 14.0 (+ or - 0.05pH). ORP range is + or - 2000.0 mV (+ or – 1.0 mV), with resolution 0.1 mV. Dissolved oxygen (DO) range is 0.0 to 500.0%; 0.00 to 50.00 mg/L (0.0 to 300.0%: + or - 1.5% of reading or + or - 1.0% whichever is greater; 300.0 to 500.0%: + or - 3% of reading; 0.00 to 30.00 mg/L: + or - 1.5% of reading or 0.10 mg/L whichever is greater; 30.00 mg/L to 50.00 mg/L: + or - 3% of reading, with resolution 0.1% / 0.01 mg/L.

Resistivity range is 0 to 999999 Ω•cm;0 to 1000.0 kΩ•cm; 0 to 1.0000 MΩ•cm. TDS range is 0 to 400000 mg/L or ppm (the maximum value depends on the TDS factor) (+ or – 1% of reading or 1mg/L) with resolution manual: 1 mg/L (ppm); 0.001 g/L (ppt); 0.01g/L (ppt); 0.1 g/L (ppt); 1 g/L (ppt) Auto-range scales: 1 mg/L (ppm) from 0 to 9999 mg/L (ppm); 0.01 g/L (ppt) from 10.00 to 99.99 g/L (ppt); 0.1 g/L (ppt) from 100.0 to 400.0 g/L (ppt) Auto-range g/L (ppt) scales: 0.001 g/L (ppt) from 0.000 to 9.999 g/L (ppt); 0.01 g/L (ppt) from 10.00 to 99.99 g/L (ppt); 0.1 g/L (ppt) from 100.0 to 400.0 g/L (ppt). Salinity range is 0.00 to 70.00 PSU (extended Practical Salinity Scale) (+ or - 2% of reading or 0.01 PSU whichever is greater), with resolution 0.01 PSU. Seawater specific gravity range is 0.0 to 50.0 σt, σ0, σ15 (+ or - 1 σt, σ0, σ15) with resolution 0.1 σt, σ0, σ15. Atmospheric pressure range is 450 to 850 mmHg; 17.72 to 33.46 inHg; 600.0 to 1133.2 mbar; 8.702 to 16.436 psi; 0.5921 to 1.1184 atm; 60.00 to 113.32 kPa (+ or - 3 mmHg within + or - 15 degrees C from the temperature during calibration) with resolution 0.1 mmHg; 0.01 inHg; 0.1 mbar; 0.001 psi; 0.0001 atm; 0.01 kPa. Temperature range is -5.00 to 55.00 degrees C; 23.00 to 131.00 degrees F; 268.15 to 328.15K (+ or - 0.15 degrees C; + or - 0.27 degrees F; + or - 0.15K), with resolution 0.01 degrees C; 0.01 degrees F; 0.01 degrees K. Meter dimensions are 221 x 115 x 55 mm (8.7 x 4.5 x 2.2”), with probe dimensions 270 x 46 mm DIA (10.6 x 1.8" DIA), and weighs (meter) 750g (26.5 oz.) (probe) 750g (26.5 oz.).
pH testers measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists.
