PRELIMINARY EXAMINATION

HI 98140, HI 98150 and HI 98160 are state-of-the-art, hand held pH

meters, designed to provide laboratory results and accuracy under harsh

industrial conditions.

These instruments are provided with a series of new diagnostic features

which add an entirely new dimension to the measurement of pH, by

allowing the user to dramatically improve the reliability of the measurement:

• 7 automatically recognized pH buffers (pH 1.68, 4.01, 6.86, 7.01,

9.18, 10.01 and 12.45) for calibration

• pH calibration up to three (HI 98140) and five (HI 98150 &

HI 98160) calibration points

• Custom calibration by entering up to two custom buffers

• Messages on the LCD to guide the user through instrument operation

• Diagnostic features to alert the user when the electrode needs cleaning

• Outside Calibration Range warning

• Monitoring of the electrode’s aging

• User-selectable “calibration time out” to remind the user when a

new calibration is necessary.

HI 98140 and HI 98150 works with SMART amplified electrodes. These

electrodes incorporate a chip, which stores the calibration data performed

with a specific instrument.
