The HI 9828 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.
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), 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.
