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.
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.
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°C and is suited for measuring pH of samples that are at ambient temperatures. The HI12963 is suitable to use with samples that are between 0 to 80°C.
The spherical bulb is for general purpose use. Other tip shapes include conic for penetration and flat tip for surface measurements.
A titanium body increases immunity to electrostatic and magnetic fields. It also allows for strong corrosion resistance, even in seawater.
This type of junction is often used on electrodes with gelled electrolytes. The advantage of this junction is it is renewable; as the cloth-like material is pulled out from its position, the junction is renewed with an uncontaminated, fresh surface.
Quick Connect DIN connector
The HI12963 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
