Multiparameter Bench Meters

The instrument is a state of the art, professional bench meter with a graphic LCD, designed to provide accurate laboratory results.

This instrument can also measure with ORP electrodes (pH channel input), thanks to their capability to measure mV with a resolution up to 0.1 mV and with ISE electrodes on ppm scale (pH channel input).
The electrode type and unit selection capability and the ISE calibration in up to five calibration standard solutions make this instrument very useful for a large range of concentration solutions measurements.
Relative mV feature is available as well as measurement in resistivity, TDS and salinity on the EC channel.

Multiparameter Water Quality Portable Meter
The Multiparameter Portable Meter is a comprehensive analytical instrument, 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. Some of the most advanced capabilities available are incorporated into this portable meter.
Designed for intuitive operation, the menu-driven navigation is user-friendly and logical. A backlit 128 x 64 pixels graphic 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, provides high-quality resolution and sophistication that is unsurpassed in its class.
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 actually 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! While in calibration mode, the meter will also assess and verify probe functionality.
For monitoring and recording data, HI 9828 can be equipped with the optional T.I.S. - Tag Identification System: iButton©s with unique ID numbers.
Installed at any sampling site, these tags will record and match specific location information with 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 connected sensors and log-on-demand & automatic logging can record up to 60,000 data samples. All data is downloadable to a PC via USB connectivity.
it is designed for demanding outdoor environments.
The meter is impact resistant and waterproof to IP67 standards (30 minutes immersion under 1 m of water), and the multi-sensor probe, HI 769828, with an IP68 rating, can be left underwater for an extended period of time.
This 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.
Five out of six measured parameters are housed in the probe: pH/pH mV, ORP, EC, % saturation and mg/L (ppm) oxygen and temperature.
Each sensor is independently replaceable, and easy to maintain & clean.
The sensors are protected by a rugged outer PVC/stainless steel sleeve, the design of which is suited for use in 2" wells.
The intact probe housing is rated to IP68. Standard cable lengths are 4, 10 and 20 meters and custom lengths are available upon request.
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 determinations are possible with measurements from this 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. It accepts both alkaline and rechargeable batteries and can be recharged in the field via the 12V car accessory outlet adapter, included.
Order Information:

it is supplied with multisensor probe (pH/ORP, EC, DO, temperaure), quick calibration standard solution (500 mL), probe maintenance kit, rechargeable C size Ni-MH batteries (4), power adapter & cable, car 12V accessory outlet adapter, USB interface cable, Windows® compatible software and instruction manual in a rugged carrying case.
