The HI12973 is a  gel-filled, single reference junction, titanium pH electrode for water treatment with a Quick DIN connector. This sensing portion of this electrode is made with general-purpose glass. The HI12973 also has a cloth 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 HI991002 and HI991003 pH meters.
  • Titanium Body
  • Built-In Temperature Sensor
  • 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 pH electrode for water treatment 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 the pH of samples that are at ambient temperatures. The HI12973 titanium pH electrode for water treatment 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

A cloth or fiber wick junction provides a larger surface area than a standard ceramic junction. This is useful when measuring the pH of liquid samples with higher solids content.

 

Quick DIN Connector

The HI12973 uses a Quick DIN connector. This type of connector is generally proprietary to the meters they are supplied with and may not be interchangeable. Other types of connectors include BNC, screw type, T-type, and 3.5mm to name a few.
