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

Hanna HI12301 Digital PEI Body pH Electrode is a robust and high-performance solution designed for accurate and reliable pH measurement across demanding laboratory, industrial, and field applications. Built with a durable PEI (polyetherimide) body, this electrode is engineered to withstand chemical exposure, mechanical stress, and rugged handling, making it ideal for environments such as water treatment plants, environmental monitoring sites, agricultural testing fields, and industrial laboratories where long-term reliability is essential. With a wide working pH range of 0 to 13, it supports versatile testing across most aqueous samples, ensuring consistent performance in diverse applications.

The electrode features a double junction, gel-filled reference system that enhances measurement stability and prevents contamination from complex or aggressive samples, thereby extending the lifespan of the probe. Its spherical glass sensing tip ensures fast response and precise readings, while the ceramic junction maintains a steady electrolyte flow, reducing clogging and minimizing maintenance requirements. This makes it particularly suitable for routine testing workflows where accuracy and efficiency are critical.

Equipped with an integrated temperature sensor, the HI12301 automatically compensates for temperature variations within a range of -5 to 70°C, ensuring accurate and repeatable results under changing environmental conditions. The built-in matching pin works with the Sensor Check™ feature to provide advanced diagnostics, allowing users to monitor electrode condition and maintain measurement integrity over time.

The digital design incorporates an onboard microchip that stores essential data such as sensor type, serial number, and calibration history, streamlining calibration processes and improving traceability in professional settings. It connects via a proprietary 3.5 mm digital connector and includes a 1-meter cable for convenient handling during testing. With a pressure tolerance of up to 2 bar, it can also be used in pressurized systems, adding further flexibility for industrial applications.

Widely used in water and wastewater analysis, environmental research, agriculture, and industrial quality control, this electrode delivers a powerful combination of durability, precision, and smart functionality, making it a reliable choice for professionals who require accurate pH measurement in challenging conditions. pH Electrodes
