Description

The HI12973 is a titanium body, gel filled, single reference junction pH electrode with a quick connect DIN connector. This sensing portion of this electrode is made with general purpose glass. The HI12973 also has an extendable cloth type junction along with a built-in temperature sensor and amplifier within a single probe design.
This design consideration is ideal for measuring the pH in municipal and industrial wastewater, swimming pools, and various field applications. The HI12973 is designed for use with Hanna’s HI991003 pH meters.
Titanium Body
Built-In Temperature Sensor
Extendable Cloth Junction
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 HI12973 uses general purpose (GP) glass, spherical bulb, titanium body, and cloth junction with gel electrolyte.
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 HI12973 is suitable to use with samples that measure from 0 to 80°C.
Spherical Bulb
The spherical bulb is for general purpose use. Other tip shapes include conic for penetration and flat tip for surface measurements.
Titanium Body
A titanium body increases immunity to electrostatic and magnetic fields. It also allows for strong corrosion resistance, even in seawater. Out titanium bodied electrodes’ outer casings also serve as a matching pin. A matching pin is a differential measurement technique used to eliminate ground loops and common mode perturbations for the measurement system. In a system without a matching pin, electrical currents in the samples can affect the reference half cell voltage. The matching pin isolates these current/magnetic fields from the reference electrode for safe, precise pH measurements.
Cloth Junction
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 HI12973 uses aquick connect DIN connector. This type of connector is generally proprietary to the meters they are supplied with and may not be interchangeable. Other type of connectors include BNC, screw type, T-type, and 3.5mm to name a few.
