Hanna HI12303 Gel Filled PEI Body pH Electrode

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

The Hanna HI12303 Gel Filled PEI Body pH Electrode is a combination pH electrode designed for reliable, general-purpose measurements across laboratory and field environments. With a durable PEI (Polyetherimide) body, gel-filled electrolyte, and a Quick Connect DIN connector, this probe ensures fast, accurate, and maintenance-free pH analysis. Additionally, it includes an integrated temperature sensor and internal amplifier, enhancing performance in demanding or low-conductivity samples.

Key Features

• Delivers Accurate Readings with Temperature Compensation
  The HI12303 includes a built-in temperature sensor, enabling automatic compensation for temperature variations during pH measurement.

• Reduces Interference with Built-In Amplifier
  Its internal amplifier strengthens the signal, improving stability and accuracy, especially in noisy or electrically charged environments.

• Minimizes Maintenance with Gel Electrolyte
  The sealed, gel-filled design eliminates the need for refilling, offering a clean and convenient user experience.

• Ensures Rugged Performance with PEI Body
  The durable PEI construction resists chemical exposure and mechanical stress, making this electrode ideal for field and harsh lab conditions.

• Features Spherical Tip for Versatile Applications
  A 7.5 mm diameter spherical glass tip allows smooth contact with both liquid and semi-solid samples.

• Supports Fast Connection with Quick Connect DIN
  The DIN connector provides secure attachment and quick installation with compatible meters such as Hanna’s edge® series.
