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

HI9810302 is a professional wireless pH tester, part of 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 agricultural, hydroponics, and greenhouse growers that need to monitor the pH of the soil.

Operating Modes
The HI9810302 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 rugged PVDF electrode body is easy to clean. Resistant to most chemicals (e.g. solvents, sodium hypochlorite), ultraviolet light, and fungal growth, the PVDF body also has high‑abrasion resistance and mechanical strength.
• The conical tip allows for easy penetration into solids and semisolids.
• The PVDF outer junction sleeve can be removed and cleaned. Once cleaned, a small amount of supplied gel electrolyte is added and the junction is refreshed, improving the measurement and extending the life of the tester.
• 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.
• 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. Remove the probe from the plastic storage cap. 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

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.

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 ON/OFF button until “CAL MODE” is displayed.

3. When “7.01 USE” or “6.86 USE” is displayed (“CAL” tag blinking), place the electrode tip 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 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 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.

MEASUREMENT

The pH tester allows direct testing in the soil without taking samples or creating a slurry.

1. Inspect the pH probe to ensure the bridge electrolyte gel has not dried out. Refill if necessary.
2. Calibrate the pH tester.
3. Using an auger (HI721319), make a 20 mm (0.78”) hole down into the soil. The hole needs to be the same depth each time to avoid pH discrepancies.
4. Add some distilled or deionized water to the hole; the soil should be damp but not saturated.
5. Rinse the electrode with tap water and insert into the hole.
6. Allow for the reading to develop or stabilize.
7. After measurement, gently rinse off leftover soil (avoid using cloth or wipe).
   Note: Direct soil pH testing is not recommended if the ground is stony or hardened as the electrode can be damaged. If the soil is stony or hard, take a representative soil sample and add HI7051 Soil preparation solution.

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 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.
  Refilling the Electrode

• To remove the electrode sleeve, carefully rotate and slide it off (A). Set it to one side.
  Note: Handle the probe with care, the pH electrode stem is made of glass.

• Rinse off any traces of electrolyte gel from sleeve. Soak the electrode tip in HI70061 General purpose cleaning solution (or HI700661, HI700663, HI700664) for 20 minutes. Rinse with distilled or deionized water.

• Refill the reference well with HI9071 Gelled bridge electrolyte (B).

• Replace the sleeve. Ensure the o-ring is fixed inside the electrode. Rinse off excess gel with distilled or deionized water.

• Shake the probe down gently to eliminate any trapped air bubbles.

• Soak the probe in HI70300 Electrode storage solution for a minimum of 30 minutes before calibrating.

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