Hanna pH Electrode for Direct Soil Measurement - HI12923

Hanna Instruments HI12923 is a high-quality direct soil pH electrode, engineered specifically for environmental and agricultural testing laboratories. This glass body, refillable, single junction pH electrode features a low temperature (LT) conic tip, optimized for direct measurement in soils, soil slurries, and soil solutions.

• Precision triple ceramic junction ensures rapid ionic exchange and reliable performance even in high-resistance media.
• Conic glass sensing tip (12 x 12 mm) with LT glass formulation enhances measurement response time in cooler and complex soil samples.
• Integrated amplifier and built-in temperature sensor enable accurate, fully temperature-compensated pH readings, eliminating interference from electrical noise or signal drift.
• Refillable with standard 3.5M KCl with AgCl electrolyte for extended service life and ease of maintenance.
• Robust glass body guarantees chemical resistance and straightforward cleaning between uses.

Ideal for direct soil pH measurement, this electrode interfaces with a quick-connect DIN connector and a 1 m (3.3 ft) cable, suitable for field and lab-based operations. The HI12923 is recommended for use with Hanna’s HI99121 portable pH meter, and supports applications ranging from agricultural soil analysis to environmental monitoring.

• Measurement range: pH 0 to 12, operating temperature: -5 to 70°C (23 to 158°F).
• Maximum pressure: 0.1 bar, outer diameter: 12 mm, body length: 120 mm, overall length: 175.5 mm.
• Conforms to requirements for laboratory and industrial soil pH analysis procedures.

This electrode enhances accuracy and repeatability in settings where direct measurement is crucial, such as soil nutrient management, precision agriculture, and lab-based environmental assessment.
