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.

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 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
