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.

Instruction Manual

HI 98129 - HI 98130

Waterproof pH, EC/TDS &

temperature meters

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:
• 4 x 1.5V batteries
• HI 73127 pH electrode
• HI 73128 Tool to remove the pH electrode

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

and 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

(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/

TDS.
Measurements are highly accurate with a unique

stability indicator right on the LCD.
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 HI 73127 pH electrode, supplied with the meters,

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.

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 elec-

trostatic discharges. Avoid touching this glass bulb at all times.

During operation, ESD wrist straps should be worn to avoid

possible damage to the electrode by electrostatic discharges.

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.
