SPECIFICATIONS

OPERATION

• Remove the protective cap and turn

ORP on with by sliding the ON/OFF

switch on the top of the meter.

• Immerse it into the solution to

be tested, without exceeding the

maximum immersion level.

• Stir gently and wait for stable reading.

• After use, rinse the electrode with tap water and

replace the protective cap.

MAINTENANCE

• Check the meter by im-

mersing it in HI7021 test

solution. The reading should

be between 240±20 mV at

25 ºC (77 ºF).

Otherwise clean the electrode

platinum tip by rubbing it

with a lint-free cloth soaked

with HI7061 cleaning solu-

tion.

• For more accurate readings, condition the meter

by immersing it in a pretreatment reducing

(HI7091) or oxidizing (HI7092) solution for

about 30 minutes before taking measurements.

• In case of erroneous readings even after an

accurate conditioning and calibra-

tion, the reference junction might

be contaminated or clogged.

• Pull out 2 mm (1/8’’)

of the cloth junction

to renew the electrode

reference (it is recom-

mended to cut the cloth

leaving always at least

2 mm -1/8’’ over the

reference compartment).

Repeat the maintenance and conditioning

procedure.

The cloth junction can be pulled out approxi-

mately 20 times. After that, the electrode should

be replaced.

ELECTRODE REPLACEMENT

For replacing the electrode, contact your local

Hanna Instruments Office.

BEPS & BATTERY REPLACEMENT

The meter is provided with BEPS (Battery Error

Prevention System) which avoid any erroneous

reading due to low battery level, by automatically

switching the meter off.

To replace the batteries, slide off the battery

compartment cover and replace all four 1.5V

alkaline batteries, while paying attention to the

correct polarity.

Batteries should only be replaced in a non-

hazardous area and using the battery type specified

in this instruction manual.

Preliminary Examination

Remove the tester and accessories from the packing material and

examine it carefully. If you require any further information, please contact

Hanna Instruments technical support team at [email protected].

Note: Save all packing material until you are sure that the tester

works correctly. Any damaged or defective item must be returned

in its original packing material with the supplied accessories.

General Description & Intended Use

HI98120 is a compact ORP and temperature tester. It features a

two-buttons operation system and is easy to use. The compact and

waterproof casing is designed to float if accidentally dropped in the

water. The tester is factory calibrated and measures temperature in

both °C and °F. It displays a stability tag that will disappear once the

reading has stabilized.

Battery level and low-battery indicator are clearly displayed on

the LCD to alert the user in the event that low battery power could

adversely affect the readings.

BEPS (Battery Error Prevention System)

The tester will automatically shut off if there is not enough power to

get an accurate reading.

ORP Probe

HI98120 is supplied together with HI73120 ORP replaceable

electrode.

Temperature Sensor

The stainless steel temperature sensor facilitates faster and more

accurate temperature measurement.

Operational Guide

Turning the Tester ON / OFF

Press and hold /MODE. Al LCD segments will be displayed for a

few second followed by battery life percentage indicator (e.g. % 100

BATT).

To turn the tester OFF, from measurement mode, press MODE. “OFF”

will be displayed on the second LCD line and the tester will turn off.

HOLD Mode

From measurement mode, press and hold SET/HOLD until HOLD is

displayed. mV reading will be frozen on the LCD. Press either buttons

to resume measurement mode.

Setup

Setup mode allows the selection of temperature unit.

To enter the Setup mode, press /MODE until “TEMP“ and the

current temperature unit are displayed on the second LCD line (e.g.

“TEMP °C”).

Use SET/HOLD to change the temperature unit, and press /MODE to

return to measurement mode.

Measurement

Place the electrode in the solution to be tested while stirring it gently.

The measurement should be taken after the stability tag ( ) has

disappeared.

The ORP (mV) value is displayed on the first LCD line and the

temperature on the second LCD line.

Note: If measurements are taken successively, rinse the probe

thoroughly in distilled or deionized water to eliminate cross-

contamination. After cleaning, rinse the probe with some of the

sample to be measured.

Maintenance

Please read the information below to ensure the highest possible

accuracy.

•If measurements are taken successively, rinse the probe

thoroughly in distilled or deionized water to eliminate cross-

contamination.

•Clean the electrode monthly using by keeping the electrode in

HI7061 General purpose cleaning solution for 30 minutes and

rinsing the probe thoroughly with water.

•When not in use, add a few drops of HI70300 Storage solution to

the protective cap. Never store the probe in distilled or deionized

water.

Electrode Replacement

Use supplied removal tool (HI73128) to replace the ORP electrode.

Insert the tool into the probe cavity.

Rotate the tool counterclockwise.

Pull the electrode out by using the other side of the tool.

Insert a new ORP electrode following the above instructions in reverse

order.

Battery Replacement

Battery life percentage indicator is displayed at power on. If the

battery level drops below 5%, the symbol lights up indicating

that the batteries should be replaced soon.

If the battery level is not adequate to guarantee an accurate reading,

the tester automatically turns off.

To replace the batteries, follow the next steps:

1. Turn OFF the tester.

2. Remove the four screws on the top of the tester to open the battery

compartment (figure 1).

fig. 1

3. Remove the old batteries.

4. Insert four new 1.5V AA batteries in the battery compartment

while paying attention to the correct polarity (figure 2).

5. Close the battery compartment using the four screws.
