The HI 9828 Multiparameter Portable Meter is capable of measuring up to 13 critical water quality parameters (6 measured and 7 calculated), including pH, EC/TDS, ORP, DO, atmospheric pressure, and temperature down to 100 meter depths. Designed for intuitive operation, the menu-driven navigation is user-friendly and logical. A large backlit LCD, that automatically sizes the digits, allows full configuration of each measured parameter, displays on-screen graphing and has options for units and language selections.
Engineered with smart features such as auto recognition of pH/ORP probe, auto-ranging adjustments for EC/TDS readings, and measurement check – to eliminate erroneous readings – and more, our design simplifies operations and handling. There is virtually no learning curve to getting into this meter and quickly mastering it’s capabilities. Each parameter is fully supported by the on-screen contextual HELP function, which is active during measurement and calibration modes. For field applications, Hanna’s Quick Calibration allows the user to standardize pH, conductivity and dissolved oxygen, all with one solution.
For monitoring and recording data, HI 9828 can be equipped with the optional T.I.S. – Tag Identification System: iButtons with unique ID numbers. Installed at sampling site, these tags will record and match specific location information while logging data. Comprehensive GLP features, such as last calibration date and status information, calibration time-out, and date and time tags associated with sample measurements, ensure consistency and accountability. The logger function memorizes data from each sensor and log-on-demand or automatic logging can record up to 60,000 data samples. All data is downloadable to a PC via USB connectivity.
The galvanic DO sensor has a built-in thermistor to provide fast temperature corrected readings. Of course, there is no polarization time for this sensor, so it is ready for measurement at a moment’s notice. For EC, a 4-ring conductivity system ensures stable readings that are immune to polarization and the buffering effect of surface coating. Absolute conductivity, temperature corrected conductivity, salinity, specific gravity and TDS are calculated from the EC sensor. The meter automatically recognizes the presence of either the pH or pH/ORP sensor. Both sensors have a cloth junction which allows greater sensitivity, and are gel-filled for improved resistance to contamination. The meter also displays pH/mV readings, ideal for trouble-shooting.
HI 9828 is designed for demanding outdoor environments. The meter is impact resistant and waterproof to IP67 standards (30 minutes immersion under 1 m of water). The intelligent probe contains a built-in microprocessor with amplifiers, interprets the high impedance signals from each sensor and sends the converted data to the meter. Consequently, common tolerance issues associated with high impedance signals, such as limiting cable length, and noise interferences are eliminated. The probe maintains reliable communication with the meter, and the user is warned of any problems, such as a broken cable line. The sensors are protected by a rugged outer 2” PVC sleeve with stainless steel weight, and each sensor is independently replaceable. Standard probe cable lengths are 4 and 10 meters, and then all the way up to 100 meters in 10-meter intervals, custom lengths are also available. It accepts both alkaline and rechargeable batteries and can be recharged in the field via the included 12V car adapter. A hard carrying case is included and can accommodate all the accessories and probe cable lengths up to 20 meters, a second hard case is included to accommodate probes with cable lengths greater than 20 meters.
