Hanna Digital PEI Body pH Electrode with Matching Pin for Field Applications - HI12301

The HI12301 Digital PEI Body pH Electrode is a high-performance laboratory and field probe designed for reliable pH measurement across a wide range of applications. Offering a working pH range of 0 to 13, this electrode features a rugged PEI plastic body, double junction with gel-filled reference, and an integrated matching pin for advanced Sensor Check diagnosis. Ideal for harsh environments, the HI12301 delivers precise, temperature-compensated readings thanks to its built-in temperature sensor, making it suitable for field work as well as laboratory use.

This probe connects with a proprietary 3.5 mm digital connector and includes a 1 m (3.3 ft) cable for practical handling during tests. The single ceramic junction ensures a steady flow rate (15–20 μL/h), and the spheric glass tip (7.5 mm diameter) provides accurate, fast readings. The electrode stores sensor type, serial number, and calibration data in an onboard microchip, supporting optimal digital calibration workflow.

• pH range: 0–13, suitable for most aqueous environments.
• Double junction construction for enhanced measurement stability and long service life.
• PEI body resists chemical and mechanical stress for field durability.
• Matching pin compatible with Sensor Check feature for advanced diagnostics.
• Gel-filled reference cell minimizes maintenance requirements.
• Temperature operating range: -5 to 70°C (23 to 158°F).
• Maximum pressure up to 2 bar enables use in pressurized systems.

Typical applications include environmental monitoring, water and wastewater analysis, agricultural testing, and industrial laboratory setups. The integrated temperature sensor ensures accurate readings by compensating for thermal effects during measurement.
