Dear Customer,
Thank you for choosing a Hanna product. This manual
will provide you with the necessary information for a
correct operation. Please read it carefully before
using the meter. If you need additional technical
information, do not hesitate to e-mail us at
tech@hannainst.com.

These instruments are in compliance with the
directives.

Remove the instrument from the packing material
and examine it carefully. If any damage has occurred
during shipment, immediately notify your Dealer or
the nearest Hanna Customer Service Center.
The meters are supplied with:
• HI 7031 1413 µS/cm calibration solution, 20 mL

sachet (for HI 98321)

• HI 7030 12.88 mS/cm calibration solution, 20 mL

sachet (for HI 98322)

• 4 x 1.5V AA batteries
• Instruction manual

Note: Conserve all packing material until the instru-

ment has been observed to function correctly.
Any defective item must be returned in its
original packing.

HI 98321 and HI 98322 are portable EC/TDS and
temperature meters specially designed for analytical
field applications.
These meters provide fast, accurate, on-the-spot mea-
surements, with a unique stability indicator right on
the LCD.
All EC/TDS readings are automatically temperature
compensated (ATC), and temperature values can be
displayed in °C or °F units.
The EC/TDS conversion factor (CONV) is selectable by
the user, as well as the temperature compensation
coefficient 

β

 (BETA).

The meters can be easily calibrated at one point.
A low battery symbol warns the user when the batter-
ies are to be replaced. In addition the Battery Error
Prevention System (BEPS) avoids erroneous reading
caused by low voltage level by turning the meter off.
The built-in temperature and EC/TDS sensors are
protected inside the cell cup.

able interferences to radio and TV equipment.
Any variation introduced by the user to the supplied equip-
ment may degrade the instrument’s EMC performance.
To avoid electrical shock, do not use this instrument when
voltages at the measurement surface exceed 24 VAC or 60
VDC. To avoid damages or burns, do not perform any mea-
surement in microwave ovens.
