Sorting out information about common knowledge of pH meter electrodes

To do industry, you need to know more about industry, and you need to know more about other products when making terminals, so that you can expand your own understanding and design more terminals that can be matched with other industrial products.
Today we collected the relevant knowledge of PH meter, hoping to provide our customers with more information about other industries.
First of all, his invention is: in 1909, the first ph meter glass electrode announced the invention. It was not until 1939 that the researchers introduced the impedance amplifier, which really realized the application in industrial measurement. At present, only it can achieve 14 orders of magnitude ion concentration measurement with high accuracy.
It is the same as the development history of the terminal, it is also a process of improvement after a long time. Early typical ph meter measurement system includes three independent electrodes (pH measurement electrode, reference electrode and temperature electrode).
Today, such independent electrodes are rarely sold. Why is this? This is because in the 1970s, industrial pH testing was used in large quantities; however, because it is often impossible to diagnose the problem, the measurement electrode or the reference electrode, users You can only judge by yourself;
At the same time, the loading and maintenance of the reference electrode is also disturbing to the user.
The life problem of the pH electrode is collected. In some applications, the glass electrode is easily corroded, blocked, scraped and worn, which will greatly shorten the life of the electrode. Solving these problems depends on updating the higher-end electrode design.
Supu has also produced terminal blocks for nearly 20 years. It is also a manufacturer of high-quality terminal blocks in the industry. Although we do not produce pH meters, we are willing to understand the different characteristics of different industries and grow together with global industrial manufacturers.

Waterproof Vertical Mount D-Sub Connectors


waterproof D-sub system is IP67 rated. These panel-mount connectors are available in solder cup as well as right angle and vertical PCB mount types. The cable-mount connector kit includes the connector, which has solder cup contacts. These connectors are available in 9-, 15-, and 25-positions in standard density and 15-, 26-, and 44-positions in high density. The recommended wire gauge for the solder cup connector is 22 AWG to 26 AWG.

These panel-mount waterproof D-subs are designed for rear-mount applications in panels that are up to 2.0 mm thick. They come with two sets of jackscrews. One jackscrew set is 5 mm long for panel thickness up to 1.2 mm, and the other is 6 mm long for panel thicknesses from 1.2 mm to 2.0 mm.

Cable mount D-sub connector kits come with the backshell, seal, thumbscrews, and solder cup connector. They are also easy to install. Simply fit the cable through the backshell, terminate the wire to the solder cup contacts, and hand tighten the cable nut on the rear of the backshell. The backshell will seal a particular range of cable diameters depending on the position count of the connector. Consult the datasheet for specific cable diameter ranges.
