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 area could cause unaccept­able interferences to radio and TV equipments, requiring the operator to take all
necessary steps to correct interferences.
The glass bulb at the end of the electrode is sensitive to electrostatic discharges. Avoid
touching this glass bulb at all time. During calibration of instruments, ESD wrist straps
should be worn to avoid possible damage to the electrode by electrostatic discharge.
Any variation introduced by the user to the supplied equipment may degrade the
instrument's EMC performance.
To avoid electrical shock, do not use these instruments when voltages at the
measurement surface exceed 24VAC or 60 VDC.
To avoid damages or burns, do not perform any measurement in microwave ovens.

GENERAL DESCRIPTION

HI98160 is a portable logging microprocessor-based pH/ORP/tempera­ture meter.

All pH measurements are automatically compensated for temperature
(ATC or MTC). The instrument housing is made of rugged, lightweight
material, making it truly portable.

Eight memorized buffers (1.68, 3.00, 4.01, 6.86, 7.01, 9.18, 10.01
and 12.45 pH) and wrong buffer recognition technology make pH
calibration simple and error free. One or two-point procedure can be
performed.

The meter is also equipped with a stability indicator and backlight
feature for comfortable reading even in excessively dark environments.

An user friendly interface provides clear messages regarding errors,
functions and more.

The GLP features provide a guarantee of data consistency.
Measurements can be performed with lab-grade precision in the field as

well as in the laboratory.
An alarm time-out is available to alert the user if too much time has

elapsed since the last pH calibration and that re-calibration may be
required.

The meter provides a controlled access to calibration and GLP settings
through a password protection method.

The Battery Error Preventing System (BEPS) recognizes batteries level
and automatically switches the meter off when batteries are too weak
to support proper function.

To prolong battery life, the backlight feature is automatically disabled
when the batteries are getting low; a clear indication is displayed on
LCD to warn the user of this condition. However, the meter continues
to measure correctly even when the low battery indication is dis­played.

The meter can store measurements in memory upon user request for
retrieval at a later time.

HI98160 also allows transfer of data to computer through the RS232
interface.

In addition, the meter allows the user to enter an ID code to uniquely
identify the instrument.
Made of tough, lightweight ABS material, the water-resistant rugged
casing is built to last.
The meter is in compliance with IP67 standards: dust-tight, pro-
tected against the effects of temporary immersion in water and
designed to provide laboratory results and accuracy under harsh
industrial conditions.

For refillable electrodes:

Refill it with fresh electrolyte (HI7071 for single junction or HI7082 for
double junction). Allow the electrode to stand upright for 1 hour.

Follow the Storage Procedure above.

CLEANING PROCEDURE

General Soak in Hanna HI7061 General Cleaning Solution for
approximately 1 hour.

Removal of films, dirt or deposits on the membrane/junction:

- Protein Soak in Hanna HI7073 Protein Cleaning

Solution for 15 minutes.

- Inorganic Soak in Hanna HI7074 Inorganic Cleaning

Solution for 15 minutes.

- Oil/grease Rinse with Hanna HI7077 Oil and Fat Cleaning

Solution.

IMPORTANT: After performing any of the cleaning procedures rinse

the electrode thoroughly with distilled water, drain and refill the
reference chamber with fresh electrolyte, (not necessary for GEL filled
electrodes) and soak the electrode in HI70300 Storage Solution for
at least 1 hour before taking measurements.

TROUBLESHOOTING

Evaluate your electrode performance based on the following possibilities.

• Noise (Readings fluctuate up and down) could be due to:

- Clogged/Dirty Junction: Refer to the Cleaning Procedure above.

- Loss of shielding due to low electrolyte level (in refillable
electrodes only): refill with fresh HI7071 for single junction or
HI7082 for double junction electrodes.

• Dry Membrane/Junction: Soak in Storage Solution HI70300

for at least 1 hour.

• Drifting: Soak the electrode tip in warm Hanna Solution
HI7082 for one hour then flush tip with distilled water. Refill with

fresh HI7071 for single junction electrodes and HI7082 for double
junction electrodes.

• Low Slope: Refer to the cleaning procedure above.

• No Slope: Check the electrode for cracks in glass stem or bulb

and replace the electrode.

• Slow Response/Excessive Drift: Soak the tip in Hanna Solu­tion HI7061 for 30 minutes, rinse thoroughly in distilled water
and then follow the Cleaning Procedure above.
