Waterproof
pH & Temperature Meters
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
• 4 x 1.5V batteries
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 98127 and HI 98128 are waterproof pH and
temperature meters. The housing has been completely
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 memorized
buffer values.
Measurements are highly accurate with a unique sta-
bility 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 meters,
is interchangeable and can be easily replaced.
The stainless steel encapsulated temperature sensor fa-
cilitates faster and more accurate temperature
measurement and compensation.

Recommendations for Users
Before using this product, make sure that it is
entirely suitable for the environment in which it is
used.
The glass bulb at the end of the electrode is sensitive
to electrostatic discharges. Avoid touching the glass
bulb at all times.
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.
