Hanna pH Electrode for Direct Soil Measurement - HI12923

Hanna Instruments HI12923 Direct Soil pH Electrode is a high-performance and precision-engineered sensor designed specifically for accurate pH measurement in soil, soil slurries, and soil solutions. Ideal for agricultural, environmental, and laboratory testing applications, this electrode delivers reliable and repeatable results even in complex and high-resistance sample matrices. Its robust glass body construction ensures excellent chemical resistance and durability, making it suitable for both field and laboratory use.

The electrode features a conical low temperature (LT) glass sensing tip (12 × 12 mm), optimized for direct insertion into soil and semi-solid samples. This design enhances responsiveness and ensures accurate measurements in cooler environments and challenging soil conditions. The advanced triple ceramic junction provides a high electrolyte flow rate, ensuring stable ionic exchange and minimizing clogging, which is critical for maintaining measurement consistency in particulate-rich samples.

Equipped with an integrated amplifier and built-in temperature sensor, the HI12923 offers automatic temperature compensation and improved signal stability, reducing electrical noise and drift during measurements. This ensures precise and dependable readings across varying environmental conditions. The refillable single junction Ag/AgCl reference system allows the use of 3.5M KCl with AgCl electrolyte, enabling easy maintenance and extended electrode life.

The electrode operates within a pH range of 0 to 12 and a temperature range of -5 to 70°C, making it versatile for a wide range of soil analysis applications. Its compact dimensions, including a 120 mm body length, 175.5 mm overall length, and 12 mm diameter, ensure compatibility with standard laboratory setups. The quick-connect DIN connector and 1 meter cable provide secure and convenient integration with compatible instruments such as the HI99121 portable pH meter.

Widely used in precision agriculture, soil nutrient management, environmental monitoring, geotechnical analysis, and research laboratories, the Hanna HI12923 pH Electrodes is an essential tool for professionals requiring accurate and direct soil pH measurement. Enhance your analytical capabilities with Hanna’s advanced electrode technology, designed for durability, precision, and consistent performance in demanding soil testing environments.
