Hanna pH Electrode for Direct Soil Measurement - HI1292D

The HI1292D pH Electrode for direct soil measurement is a specialized laboratory probe designed for precise pH readings in soil samples and soil solutions. With a durable glass body and refillable single junction, the HI1292D ensures long-term accuracy and robust performance in demanding agricultural, research, and environmental testing applications.

Equipped with a triple ceramic junction in the outer reference cell, this electrode provides a stable and consistent electrolyte flow (40-50 µL/h), essential for accurate pH measurement in complex soil matrices. The low temperature glass conic tip (12 x 12 mm) enhances responsiveness and facilitates easy penetration into soil slurries for reproducible results.

• Glass construction for excellent chemical resistance in laboratory and field soils applications.
• Refillable electrode with 3.5M KCl + AgCl electrolyte for customizable maintenance.
• Integrated amplifier and built-in temperature sensor for automatic compensation and robust signal transmission, minimizing noise.
• Body length: 120 mm; overall length: 175.5 mm; outer diameter: 12 mm.
• Max pressure: 0.1 bar ensures safety during soil insertion.
• Measurement range: pH 0 to 12 makes it versatile for various soil types.
• Temperature operation from -5°C to 70°C supports field and laboratory use.
• Cable: 1 meter (3.3 ft), 7-pole DIN connector provides flexibility and secure connection.

The HI1292D is ideal for use with Hanna’s HI99121 portable pH meter and other meters with a compatible DIN connector. Recommended for direct soil pH measurement, testing soil samples, and monitoring soil solutions in agricultural, environmental, geotechnical, and research labs.

Industrial, laboratory, agriculture, and environmental applications can rely on this electrode for high precision and repeatable soil pH measurements. Explore more professional laboratory pH electrodes and accessories in the pH Electrodes category on EnvMart.
