2 3
GENERAL DESCRIPTION
HI 9126 is a state-of-the-art waterproof, heavy-duty pH meter designed
to provide laboratory results and accuracy under harsh industrial
conditions.
A large multil-level LCD, with clear indications related to the electrode and
instrument status, pH and temperature displayed simultaneously, and
user friendly graphic symbols during calibration.
This meter is provided with a series of new diagnostic features which add
an entirely new dimension to pH measurement, 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 (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 you when a new
calibration is necessary
HI 9126 can also measure for Oxidation Reduction Potential in the mV
range with a resolution of 0.1 mV.
It offers an extended temperature range from –20 °C (–4 °F) to 120 °C
(248 °F).
