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 crosscontamination. 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 crosscontamination.
• 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).
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.

Note: Only use the battery type specified in the manual. Old batteries should be disposed in accordance with local regulations.
