Titanium Body pH Electrode for Wastewater with Quick Connect DIN Connector - HI12963


In stock

The HI12963 is a titanium body, gel filled, single reference junction pH electrode that has a built-in temperature sensor and a quick connect DIN connector. This type of connector is proprietary to specific meters such as the HI98190 and HI991001.

The HI12963 electrode is made with general purpose glass and has an extendable cloth type junction. The design considerations are ideal for measuring the pH in industrial, municipal, and environmental applications.

  • Titanium Body
  • Built-In Temperature Sensor
  • Quick Connect DIN 


Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.

The HI11103 uses general purpose (GP) glass, spherical bulb, glass body, single ceramic frit, single junction and is gel filled.

GP glass

General Purpose Glass Formulation

General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25℃ and is suited for measuring pH of samples that are at ambient temperatures. The HI11103 is suitable to use with samples that are between 0 to 80℃.

GP glass

Spherical Bulb

The spherical bulb is for general purpose use. Other tip shapes include conic for penetration and flat tip for surface measurements.

glass body

Glass Body

The glass body is ideal for laboratory use. The glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The faster the electrode reaches equilibrium, the steadier the reference potential.

single ceramic junction

Single Ceramic Junction Reference

The HI11103 is a single junction pH electrode. The junction also known as a salt bridge is necessary component of the electrical circuit. The movement of ions must flow through the junction for a steady reading. The reference cell has a single ceramic frit. The ceramic is a porous material that is easily fused with the glass body and has a similar expansion coefficient. A single ceramic junction has a flow rate of 15-20 μL/hour. Other junction types are available with higher flow rates and made with different materials.

gel filled pH electrode

Gel Filled

The HI11103 is a glass body, laboratory pH electrode that uses a gel electrolyte. The gel filled probe is ideal for the lab that wants maintenance-free operation other than routine cleaning and calibration. The HI11103 does not require a refill electrolyte solution.

din connector

Quick Connect DIN Connector

The HI11103 uses a Quick Connect DIN connector that makes attaching and removing the probe simple and easy. This type of connector is proprietary to the meter. See specifications table for compatible meters.
