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.

GENERAL DESCRIPTION

HI 9026 is a state-of-the-art waterproof, heavy-duty pH meter designed to
provide laboratory results and accuracy under harsh industrial conditions.
This meter is provided with a series of new diagnostic features which
add an entirely new dimension to the measuremeny of pH, by
allowing the user to dramatically improve the reliability of the
measurement:
 7 memorized buffers (pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01

and 12.45) for calibration
 Custom calibration by entering up to two custom buffers
 Messages on the LCD to make the calibration easy and accurate
 Diagnostic features to alert the user when the electrode needs

cleaning
 Monitoring of the electrode aging
 User-selectable calibration time-out to remind when a new

calibration is necessary
HI 9026 can also measure with ORP electrodes, thanks to its capability
to measure mV with a resolution up to 0.1 mV.
Moreover, it offers an extended temperature range from 20 °C (4 °F)
to 120 °C (248 °F), using HI 7662 interchangeable probes.
