SPECIFICATIONS

• Available with Hanna Lab App ** Measuring outside the recommended operating temperature range may damage the gel electrolyte and void product warranty.

Note: The tester can display measurements from –2.00 to 16.00 pH. Measurements outside of the pH range will flash. In this case assess the integrity of the tester and the type of measured sample.

GENERAL DESCRIPTION & INTENDED USE

HI9810352 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 designed to measure the pH of sushi rice and ensure it meets the food-hygiene and Hazard Analysis Critical Control Point (HACCP) regulations.

Operating Modes

The HI9810352 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 titanium body offers protection from accidental breakage. Rugged and resilient, the titanium works as an electronic shield protecting against interferences from electrical noise or humidity. The flat glass tip provides optimal surface contact for sushi rice pH measurements and for surfaces that cannot be penetrated. The open junction reference resists clogging due to the hard gel surface (violence) that is used for the reference cell. When the junction becomes coated with starch from the rice, clean the probe to expose the violence reference. The double junction design presents a silver-free electrolyte solution interacting with the sample, making the electrodeless susceptible to clogging and guaranteeing a fast response and stable reading. 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 pH 7.01 buffer (or pH 6.86). To restore factory defaults, press and hold the ON/OFF button. “CAL CLR” is displayed.

Note: It is recommended to calibrate the electrode with buffers at the temperature it will be used at. App Store is a trademark of Apple, Inc. Google Play and the Google Play logo are trademarks of Google LLC.

Stand-Alone Tester (Up to Three-Point Calibration)

1. Rinse the electrode tip with purified water and blot dry. Then rinse with the buffer being used for calibration.
2. Press and hold the ON/OFF button until “CAL MODE” is displayed.
3.  When “7.01  USE” or “6.86  USE” is displayed with the “CAL” tag blinking, place the tip of the electrode in the correct buffer.
4. When the buffer has been recognized, “REC“ is displayed. “WAIT” 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. “CAL SAVE” 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, “CAL SAVE” 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, “CAL SAVE” 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.

SUSHI RICE MEASUREMENT

The application-specific electrode design allows for direct measurement of sushi rice and measurement of rice slurries.

Preparation

• Calibrate the tester prior to measurement. Refer to the calibration section for details.
• Loosen the threaded top collar counterclockwise before removing the probe from the storage cap.
• After measurement, place the probe tip into the cap and gently tighten the threaded collar.
• Do not be alarmed if salt deposits or storage solutions are present. Rinse the electrode with purified water.
• If the glass and/or junction are dry, soak the electrode in storage solution (or pH 4.01 or pH 7.01 buffer solution) for a minimum of 30 minutes.
• After conditioning, rinse with water and blot dry.

Direct Measurement

1. Rinse the electrode tip in water, shake gently to dry, and insert into the sushi-rice surface.
2. Wait for stable measurement. Stability indicator (#) stops blinking when a stable measurement has been reached.
3. Rinse the electrode in distilled (or deionized) water and repeat if necessary.

Measurement of Rice Slurries

1. Mix into a white slurry one part seasoned rice (representative sample) and two parts distilled water for about 30 seconds.
2. Pour the slurry mixture into a container. With the calibrated tester verify the reading has stabilized (stability indicator -#- has disappeared) and the measured value is within the accepted window for acidified rice.
3. If the reading is outside the accepted window add more sushi seasoning and mix thoroughly and evenly. Rinse the electrode tip in purified water and repeat the measurement.
4. Note: Follow local food-authority guidelines for information on recommended ratios of rice and water, and pH limit for sushi rice.

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 a 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 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

1. “—- WRONG” displayed during calibration. Invalid buffer. Check the buffer value and use a fresh buffer.
2. The measured value displayed blinking. The measured value is out of electrode range. Clean the electrode to improve the condition.
3. Battery icon (!) displayed blinking. The battery is below 10 %, replace the battery.
4. “BAtt DEAD” and the tester turns off. Depleted battery, replace the battery.
