WARRANTY
HI 98129 and HI 98130 are warranted for one
year against defects in workmanship and materials
when used for their intended purpose and maintained
according to instructions. The electrode is war-
ranted for a period of six months. This warranty is
limited to repair or replacement free of charge.
Damages due to accident, misuse, tampering or lack
of prescribed maintenance are not covered.
If service is required, contact the dealer from whom
you purchased the instrument. If under warranty,
report the model number, date of purchase, serial
number and the nature of the failure. If the repair is
not covered by the warranty, you will be notified of
the charges incurred. If the instrument is to be re-
turned to Hanna Instruments, first obtain a Returned
Goods Authorization Number from the Customer
Service department and then send it with shipment
costs prepaid. When shipping any instrument, make
sure it is properly packaged for complete protection.
All rights are reserved. Reproduction in whole or in
part is prohibited without the written consent of the

Instruction Manual
HI 98129 • HI 98130
pH/EC/TDS/Temperature
with Only One Tester
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 [email protected].
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.
Each meter is supplied with:
• HI 73127 pH electrode
• HI 73128 electrode removal tool
• batteries (4 x 1.5V) and instructions
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.
PRELIMINARY EXAMINATION
HI 98129 and HI 98130 are waterproof pH/EC/
TDS/temperature meters. The housing has been com-
pletely sealed against humidity and designed to float.
All pH and EC/TDS readings are automatically tem-
perature compensated (ATC), and temperature values
can be displayed in °C or °F units.
For EC/TDS readings, the EC/TDS conversion factor
(CONV) is selectable by the user, as well as the
temperature compensation coefficient β (BETA).
The meters can be calibrated at one or two points for
pH (with auto-buffer recognition and against five
memorized buffer values), and at one point for EC.
Measurements are highly accurate with a unique
stability indicator right on the LCD.
These meters are also provided with battery level
indication at start-up, and with a low battery symbol
which warns the user when the batteries need 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 HI 73127 pH electrode, supplied with the meter,
is interchangeable and can be easily replaced by the
user.
The stainless steel encapsulated temperature sensor
facilitates faster and more accurate temperature mea-
surement and compensation.
GENERAL DESCRIPTION
FUNCTIONAL DESCRIPTION SPECIFICATIONS
Recommendations for Users
Before using this product, make sure that it is entirely suit-
able for the environment in which it is used. Operation of
this instrument in residential areas could cause unaccept-
able interferences to radio and TV equipment.
The glass bulb at the end of the electrode is sensitive to
electrostatic discharges. Avoid touching this glass bulb at
all times.
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 volt-
ages at the measurement surface exceed 24 Vac or 60 Vdc.
To avoid damages or burns, do not perform any measure-
ment in microwave ovens.
