Hanna Gel Filled PEI Body pH Electrode with Quick Connect DIN Connector - HI12303

Hanna Instruments HI12303 Gel Filled Polyetherimide (PEI) Body pH Electrode is engineered for precision in laboratory and field pH measurement applications. With a robust PEI plastic body designed to resist chemicals, the HI12303 features a double junction reference system (Ag/AgCl) to extend operating life, especially in solutions with heavy metal ions or organics.

The electrode is equipped with a built-in temperature sensor that ensures automatic temperature compensation, enhancing accuracy in diverse conditions. Its spheric tip, crafted from low temperature glass (7.5 mm diameter), makes it suitable for portable meters and a range of temperatures (0–70°C). The innovative single ceramic junction delivers a controlled flow rate of 15–20 µL/hr, and the gel-filled electrolyte design reduces maintenance efforts.

• Durable PEI body for increased protection and chemical resistance.
• Double junction reference cell offers enhanced durability and reduced contamination risk.
• pH measurement range from 0 to 13 for broad sample compatibility.
• Temperature compensation from 0 to 70°C via the integrated temperature sensor.
• Quick connect DIN connector for secure, proprietary connection to meters such as HI98190.
• 1 m (3.3 ft) five-pole cable for easy instrument setup and mobility.
• Spherical sensing tip protected by PEI fins supports reliable measurement and portability.
• Easy to clean and maintain, requiring only standard calibration procedures.

Ideal for laboratory, field, and water quality testing in environmental, agricultural, industrial, and educational settings. This electrode enables accurate and long-lasting performance where robustness and precision are essential.
