HI12923 | Hanna pH Electrode for Direct Soil Measurement

Take the guesswork out of agricultural analysis with the Hanna HI12923 pH Electrode, a specialized probe designed for the direct measurement of pH in soil, soil slurries, and compost in Pakistan. Unlike standard spherical bulbs that risk breakage when pushed into the ground, the HI12923 features a rugged Conic Tip made of durable low-temperature glass, allowing it to easily penetrate moist soil and semi-solids without needing to prepare a liquid slurry first.

This professional-grade sensor is the replacement probe for the popular HI99121 Portable Soil pH Meter. It is engineered with a Triple Ceramic Junction, which allows a higher flow rate of electrolyte (40-50 µL/hour) compared to standard probes. This ensures a stable and fast connection between the electrode and the soil sample, even in low-moisture conditions where other probes fail. The built-in Temperature Sensor provides Automatic Temperature Compensation (ATC), ensuring your readings are accurate regardless of the weather in the field.

Frequently Asked Questions:

• Q: Can I plug this into any pH meter?

  • A: No. The HI12923 uses a specialized Quick Connect DIN connector. It is designed specifically for the Hanna HI99121 portable meter. It will not fit standard BNC meters (like the HI98107 or benchtop units) unless you use a specific adapter, which is not recommended.

• Q: Why is the tip pointed (conic)?

  • A: The conic shape acts like a wedge, allowing you to push the probe directly into soft, moist soil. This saves massive amounts of time compared to the traditional method of collecting soil, drying it, weighing it, and mixing it with distilled water to make a slurry.

• Q: Is the probe refillable?

  • A: Yes. It features a refill port near the top. You should top it up with HI7071 3.5M KCl + AgCl Electrolyte Solution. Keeping the probe full ensures positive pressure, which pushes electrolyte out through the junction to clean it and maintain a stable reading.
