GENERAL DESCRIPTION & INTENDED USE

HI9810412 is a professional wireless pH tester, part of the Hanna Instruments HALO2 family.

• The integrated Bluetooth module allows the tester to be connected to a compatible smart device with the Hanna Lab App.
• The tester has a compact, waterproof casing, and automatic pH calibration at up to three points, or four points when used with the Hanna Lab App.
• Automatically compensated temperature readings are displayed on a large LCD.
• Accurate and easy to use, the tester is ideal for users that prefer a maintenance-free laboratory pH electrode.

Operating Modes
The HI9810412 can be used as a stand-alone pH tester or connected to the Hanna Lab App.
The Hanna Lab App turns a compatible smart device into a full-featured pH meter. Features include electrode condition, GLP with time-stamp, live readings, mV resolution, manual temperature compensation, stability criteria, calibration reminder, pH (mV) and temperature alarms, tester ID, and data sharing.
Probe Features
The HI9810412 features a non-porous glass body that is easy to clean and withstands harsh chemicals.
The double junction design presents a silver-free electrolyte solution interacting with the sample, making the electrode less susceptible to clogging and guaranteeing a fast response and stable reading.
A built-in temperature sensor at the tip of the pH electrode allows for rapid determination of the sample temperature and a high-accuracy temperature reading.

CALIBRATION

Preparation & Guidelines

1. Unscrew the top collar to vent the cap before removing the probe from the plastic storage tube. Save the cap for probe storage.
2. Rinse off any storage solution or salts that may be on the body.
3. Verify there is solution inside the pH bulb by shaking the probe down to restore continuity as the solution may have moved up the stem during shipping.
4. For best results, use a rinse beaker and a separate calibration beaker for each buffer. Discard rinsing buffers after use.

Procedure
For most applications, it is recommended to start with a pH 7.01 buffer (or pH 6.86).
To restore factory defaults, press and hold the ON/OFF button. “ is displayed.
Note: It is recommended to calibrate the electrode with buffers at the temperature it will be used at.

2. Press and hold the ON/OFF button until “ is displayed.

3. When “ or “6.86  USE” is displayed with “ tag blinking, place the tip of the electrode in the correct buffer.

4. When the buffer has been recognized, “ is displayed.
   “ is displayed with the stability indicator ( ) blinking until the reading is stable. Wait until the measurement is stored and the stability indicator disappears.

5. To save a one-point calibration and return to measurement mode, press the ON/OFF button.
   “ is displayed briefly.
   With the 2P option selected

6. Place the tip of the electrode in the second buffer rinse beaker, then in the second calibration buffer. Wait until the measurement is stored and the stability indicator disappears.

7. After the second point has been stored, “ is displayed briefly and the tester will return to measurement mode automatically.
   With the 3P option selected

8. Place the tip of the electrode in the second buffer rinse beaker, then in the second calibration buffer. Wait until the measurement is stored and the stability indicator disappears.

9. Place the tip of the electrode in the third buffer rinse beaker, then in the third calibration buffer. Wait until the measurement is stored and the stability indicator disappears.

10. After the third point has been stored, “ is displayed briefly and the tester will return to measurement mode automatically.

With Hanna Lab App (Up to Four-Point Calibration)
Connect the tester to the Hanna Lab App and follow the calibration procedure.
See the App Help section for the calibration procedure.

CARE & MAINTENANCE

• Never immerse the tester over the maximum immersion level.
• Fresh buffers should be used for each calibration. Once the sachets are opened the buffer value can change over time.
• If the electrode is slow or sluggish, soak it in the cleaning solution for 20 minutes. Rinse with water and hydrate the electrode in storage solution for a minimum of 30 minutes before calibrating.
• If measurements are taken successively, rinse the probe thoroughly in distilled or deionized water to eliminate cross-contamination between measurements.

Storage
To ensure a quick response, the glass tip and junction should be kept hydrated.

1. When not in use, add a few drops of storage solution to the storage cap. If a storage solution is not available, pH 4.01 or pH 7.01 buffer can be used.
   Note: Do not store the electrode in distilled or deionized water.

2. Place the probe tip into the cap and gently tighten the collar.

WARNING & ERROR MESSAGES
