The HI-1296D is a pH electrode with 1m cable and DIN connector suitable for wastewater.
This electrode is recommended for use with HI-991001N pH meter.
The HI-1296D uses general purpose (GP) glass, spherical bulb, titanium body, and cloth junction with gel electrolyte.
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 HI-1296D is suitable to use with samples that measure from 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. Our 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.
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.
The HI-1296D uses a DIN connector. This type of connector is proprietary to the meter. Compatible meters include the HI-991001.

An introduction to pH
pH, put simply is a measure of how acidic or basic a solution is. It is a measure of H+ions present.
pH can be measured in a number of ways including test strips, indicator solution or with a pH meter and electrode. If you want to read more about the pH and the pros and cons of these methods, you can check out our introduction guide here.
How to take a pH reading and care for your electrode
pH electrodes require the correct storage and regular calibration.
If you have a pH meter or are looking to purchase and need to find out more about the care and maintenance process then you can read our guide here. We also include a troubleshoot sections with the most reported issues and possible solutions.
