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, requiring the operator to follow all necessary steps to correct
interferences.

The glass bulb at the end of the pH 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 performance.

To avoid electrical shock, do not use this instrument when voltages at the measurement surface
exceed 24 Vac or 60 Vdc.

To avoid damage or burns, do not perform any measurement in microwave ovens.

make sure that no damage has occurred during shipment. If there is any
damage, immediately notify your dealer.

The meter is supplied complete with:

• HI 1230B pH electrode

• HI 7662 temperature probe

• pH 4.01 & pH 7.01 buffer solutions, 20 mL each

• HI 700661 cleaning solution, 20 mL sachet (2 pcs)

Note: Save all packing material until you are sure that the instrument

functions correctly. Any defective items must be returned in the original
packing with the supplied accessories.

GENERAL DESCRIPTIONGENERAL DESCRIPTION

GENERAL DESCRIPTION

GENERAL DESCRIPTIONGENERAL DESCRIPTION

HI 8424NEW is a portable microprocessor-based pH/mV/temperature meter.
It features an enhanced user interface, rainproof casing, battery percentage

indication, low battery detection, automatic shut-off, automatic calibration and
error codes to guide the user in calibration and troubleshooting.

The instrument is also equipped with an inductive system for battery recharge, with
no external contact, to ensure a watertight seal. Simply place the HI 8424NEW on
the HI 710040 battery charger (optional), without needing to open the meter or
remove the battery.

The pH calibration procedure automatically recognizes three memorized buffer
values: pH 4.01, 7.01 and 10.01.

This instrument can also measure ORP. The resolution automatically switches
from 0.1 mV to 1 mV when readings exceed ±699.9 mV.

The user can set the following parameters by entering a setup mode through
the keyboard:

• enabling or disabling the auto-off feature

• enabling or disabling the acoustic signal

• selecting the temperature unit, °C or °F
