GENERAL DESCRIPTION
The HI98192 instrument is state‑of‑the‑art, heavy‑duty conductivity meter, designed to provide
laboratory results and accuracy under harsh industrial conditions.
The USP standard compliance makes the instrument useful for pure water determination.
It is provided with a series of new diagnostic features which add an entirely new dimension to the
measurement of conductivity, by allowing the user to dramatically improve the reliability of the
measurement:
• 7 memorized standards (0.00 µS/cm, 84.0 µS/cm, 1.413 mS/cm, 5.00 mS/cm,
12.88 mS/cm, 80.0 mS/cm and 111.8 mS/cm) for calibration.
• EC calibration up to five calibration points.
• Messages on the graphic LCD for an easy and accurate calibration.
• Diagnostic features to alert the user when the electrode needs cleaning.
• User‑selectable “Outside Calibration Range” warning.
• User‑selectable “calibration time out” to remind when a new calibration is necessary.
Moreover, they offer an extended temperature range from ‑20.0 to 120.0 °C (‑4.0 to 248.0 °F),
using temperature sensor inside EC electrode.
This instrument can also measure in Resistivity, TDS and Salinity ranges. Three salinity modes are
available: % NaCl, Practical salinity and Natural seawater scale.
Other features include:
• Temperature source selection
• Temperature automatic compensation, linear or non linear user selectable
• Temperature reference selection 15 °C, 20 °C or 25 °C.
• Temperature coefficient set
• Log on demand up to 400 samples
• Auto Log feature up to 1000 records
• Auto Hold feature, to freeze first stable reading on the LCD
• Lock and user setup Fixed range selection
• GLP feature, to view last calibration data for EC, NaCl
• Probe change recognition
• PC interface
• Probe replatinization
