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.

HI 98127 and HI 98128 are waterproof pH and

temperature meters. The housing has been com-

pletely sealed against humidity and designed to float.
All pH readings are automatically temperature com-

pensated (ATC), and temperature values can be

displayed in °C or °F units.
The meters can be calibrated at one or two points

with auto-buffer recognition and against five memo-

rized buffer values.
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 suitable for the environment in which it is

used. Operation of this instrument in residential

areas could cause unacceptable 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. 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

equipment may degrade the instrument’s EMC per-

formance.

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 measurement in microwave ovens.
