PRELIMINARY EXAMINATION

Note: Save all packing material until you are sure that the instrument functions correctly. All

defective items must be returned in the original packing with the supplied accessories.

SAFETY MEASURES

Before using this product, make sure that it is entirely suitable for your specific application and for

the environment in which it is used.

Operation of this instrument may cause interference to other electronic equipment, requiring the

operator to take steps to correct interference. Any variation introduced by the user to the supplied

equipment may degrade the instrument’s EMC performance.

To avoid damages or burns, do not put the instrument in microwave ovens. For your and the

instrument’s safety, do not use or store the instrument in hazardous environments.

GENERAL DESCRIPTION

Other features include:

• Log on demand up to 200 samples (100 pH and 100 mV).

• Auto Hold feature, to freeze first stable reading on the LCD.

• GLP feature, to view last calibration data for pH.

• PC interface.

The HI98165 is a portable pH and temperature meter designed for pH measurement in cheese.

Throughout the cheese making process, pH control is critical to ensure consistent fermentation and

food safety. If the pH is too low, the cheese may be prone to a brittle or pasty texture, as well as

growth of mold after packaging. If the pH is too high, the cheese may become too firm, and can

potentially be dangerous for consumption due to the risk of pathogen formation. The pH must be

carefully monitored to detect deviation from the optimal range, which can create problems with

texture, taste and public safety of cheese.

The HI98165 meter is 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:

• Seven standard buffers (pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45) for calibration.

• pH calibration up to five calibration points (see instrument specifications).

• Custom calibration with up to five custom buffers.

• Messages on the graphic LCD for an easy and accurate calibration.

• Cal Check™ Diagnostic features to alert the user when the electrode needs cleaning.

• Optional user enabled “Outside Calibration Range” warning.

• Monitoring of the electrode aging.

• User selectable “Calibration Time Out” to remind when a new calibration is necessary.

This meter is supplied with a pH electrode specifically designed for use with cheese. The FC2423

pH electrode with a built‑in temperature sensor features a stainless steel body with a conic glass

tip which allows for penetrations into solids, semi‑solids and emulsions for direct measurement of

pH in cheese products.

OPERATIONAL GUIDE

INITIAL PREPARATION

The instrument is supplied complete with 1.5V AA (4 pcs.) batteries. For placing the batteries inside

the meter, see page 42.

Make sure that the protective micro USB cover is used when not connected to a computer to ensure

waterproof protection.

For HI98165 connect the pH/temperature electrode to the DIN connector.

Turn the instrument ON by pressing ON/OFF key.

At start‑up the display will show the Hanna Instruments logo for a few seconds followed by the

percentage indication of the remaining battery life, then enters the measurement mode.

After measurement switch the instrument off, clean the electrode and store it with a few drops of

HI70300 storage solution in the protective cap (see page 45).

The Auto Power Off feature turns the instrument off after a set period (default 30 min) with no button

pressed to save battery life. To set another period or to disable this feature, see SETUP menu on

page 23.

The Auto Light Off backlight feature turns the backlight off after a set period (default 1 min) with

no buttons pressed. To set another period or to disable this feature, see SETUP menu on page 23.

pH MEASUREMENTS

To take a pH measurement remove the electrode protective cap and simply submerge the tip of the

electrode (4 cm/1½") into the sample to be tested.

Press RANGE key to choose between pH and mV ranges.

Use MODE key to select the pH resolution.

Allow time for the electrode to adjust and reading to stabilize (hourglass symbol turns off).

OPERATIONAL GUIDE

• pH reading with the selected resolution.

• Temperature reading in the selected unit (°C or °F).

• Electrode condition during the calibration day.

• The buffers used in last pH calibration (if feature is enabled in SETUP).

• Battery level indicator.

• Available functional keys.

In order to take more accurate pH measurements, make sure that the instrument is calibrated (see

page 11 for calibration details).

It is recommended that the electrode is always kept moist and rinsed thoroughly with the sample to

be measured before use.

The pH reading is directly affected by temperature. For accurate pH measurements, temperature

must be taken into consideration. If the sample temperature is different from the temperature at

which the pH electrode was kept, allow a few minutes to reach thermal equilibrium.

On the pH screen are displayed:

TEMPERATURE MEASUREMENTS

For HI98165 the temperature sensor is connected through DIN socket.

Note: The temperature can be displayed in Celsius degrees (°C) or in Fahrenheit degrees

(°F) (see SETUP for details, page 23).

BACKLIGHT FEATURE

The instrument is provided with a Backlight feature, which can be easily toggled on and off through

the keyboard by pressing LIGHT.

Note: The backlight automatically shuts off after a set period (see SETUP for details,

page 23) with no buttons pressed.
