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

INITIAL PREPARATION
The instrument is supplied complete with batteries. See Batteries Replacement for details, page 63.
To prepare the instrument for field measurements close the serial communication socket with proper
stopper (to ensure waterproof protection).
Connect the EC probe to the DIN connector on the top of the instrument. Tighten the thread ring. Make
sure the probe sleeve is properly inserted.
Turn the instrument ON by pressing ON/OFF key.
At start‑up the display will show the Hanna logo for a few seconds followed by the percentage indication
of the remaining battery life and the “Loading Log...” message, then enters the measurement mode.
The Auto Power Off feature turns the instrument off after a set period (default 30 min) with no button
pressed to save battery life. To set another period or to disable this feature, see SETUP menu on
page 35. The instrument continues to monitor the inputs and memorize readings if the automatic
logging is enabled and started. To stop autologging press StopLog key or simply power off the
instrument by pressing the ON/OFF key.
The Auto Light Off backlight feature turns the backlight off after a set period (default 1 min) with
no buttons pressed. To set another period or to disable this feature, see SETUP menu on page 35.
MEASUREMENTS
Immerse the probe into the solution to be tested. The sleeve holes must be completely submerged. Tap
the probe repeatedly to remove any air bubbles that may be trapped inside the sleeve.
If needed, press RANGE repeatedly until the desired range (EC, Resistivity, TDS, Salinity) is selected
on the LCD.
Allow for the reading to stabilize. The main LCD line displays the measurement in the selected range,
while the temperature is displayed on the lower LCD line.
OPERATIONAL GUIDE

EC range
The conductivity range is from 0 to 400 mS/cm. The actual conductivity range (the uncompen‑
sated conductivity) is up to 1000 mS/cm. The instrument will display conductivity readings up to
1000 mS/cm.
Note: The symbol in front of the temperature reading means that the temperature can be
entered by the user (Manual option selected in SETUP, or temperature out of range).
Resistivity range
The reciprocal of the conductivity of a material is the resistivity.
TDS range
A conductivity measured value can be corrected to a total dissolved solids value using the TDS factor.
Salinity
The salinity is derived from the conductivity of a sample.
Salt % range
The percent of salinity in a sample is dependent on the sample and the salinity coefficient.
