Remove the instrument from the packing material and examine it carefully to
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)
• 9V battery
• Instruction manual
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.
HI 8424 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 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 the 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

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.
