RECOMMENDATIONS FOR USERS

Before using these products, make sure they are entirely suitable for
the environment in which they are used.

Operation of these instruments 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 instruments’ EMC performance.

To avoid electrical shock, do not use these instruments 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.

GENERAL DESCRIPTIONGENERAL DESCRIPTION

GENERAL DESCRIPTION

GENERAL DESCRIPTIONGENERAL DESCRIPTION

The HI 9124 and HI 9125 are state-of-the-art waterproof, heavy-
duty pH meters designed to provide laboratory results and accuracy
under harsh industrial conditions.

A large dual-level LCD, with clear indications related to the electrode
and instrument status, pH and temperature displayed simultaneously,
and user friendly graphic symbols during calibration.

GENERAL DESCRIPTION

The pH calibration procedure is automatic with 5 memorized buffers
(4.01, 6.86, 7.01, 9.18 and 10.01), buffer recognition and
automatic temperature compensation.

The HI 9125 can be used with ORP (Oxidation Reduction Potential)
electrodes. mV measurements automatically change from 0.1 to 1 mV
resolution when the reading reaches 700 mV.
