In 1909, the first thermal analyzer glass electrode was declared. Until 1939, when the researcher introduced an impedance reducer, the thermal analyzer electrode really completed its use in industrial measurement. It was thought in advance that the thermal analyzer market capacity was only 500 units, but the inventor still maintained this area of ​​research. By 1956, 126,000 thermal analyzers had been sold. Today, more than 100 thermal analyzer electrodes are sold every hour on a global scale.

There is no measurement method that can achieve 14 orders of magnitude ion concentration measurement like a thermal analyzer electrode, and reach such high sensitivity and accuracy. That is, from the measurement scale of 1 mol/L to 0.00000000000001 mol/L, the measurement accuracy of 0.1 to 0.001 pH values. This is the reason why it invented a hundred years later, and it still has no backwardness. In today's world, there is no second kind of analysis and detection wrist that has such a long life.

Thermal analyzer electrode development

The late model thermal analyzer measurement system contained three separate electrodes (pH measuring electrode, reference electrode, and temperature electrode). Today, this kind of independent electrode is rarely sold. Why is this? This is because in the 1970s, industrial pH detection was used in small quantities; but because it is often impossible to diagnose the problem from the measuring electrode or the reference electrode, the user can only rely on his own judgment; at the same time, the loading and protection of the reference electrode is also Let the operator be bothered.

In the 1970s, the decline of the wastewater treatment industry provided a large market for thermal analyzer products. The electrode supplier supplies a composite electrode containing the measuring electrode and reference electrode (2-in-1 electrode), and even the temperature electrode is also contained in one electrode (triple electrode). If the composite electrode is broken, people usually do no more repairs, and simply changing one can do it.

Thermal analyzer life

The life span of thermal analyzers is still not very clear at all levels. The concept of throwing is always very popular. In some cases, the electrode life can be as long as a few days or even hours. In some applications, the glass electrode is easily eroded, blocked, scratched, etc., which greatly extends the life of the electrode. The handling of these problems depends on the update of the higher-end electrode design. For example, in the case of a customer in the beer consumption category, he would force the electrode to knock on the edge of the reaction kettle so that the material hung on the electrode would be shaken off, and then the invention of the electrode would be inexplicably broken. It goes without saying that he knows nothing about the weak external structure of the glass composite electrode.

Will you use a thermal analyzer

If the user of the thermal analyzer electrode encounters any problem, the first reflection is that the performance of the electrode is not good. He seldom thinks of any fault in the practice operation. In fact, many of the important causes of the thermal analyzer problem are operations. According to statistics, only about 10% of the problems originate from the thermal analyzer electrode mass itself.

Thermal analyzer electrode protection

If you use an ordinary thermal analyzer electrode, there are ways to extend its useful life, that is, accurate protection. Before use, determine whether the solution will erode the electrode glass bulb or glass rod, whether it will block the liquid junction of the electrode (individually porous ceramic); after careful use of the cleaning, if necessary, use a suitable cleaning agent.

Will you operate your own thermal analyzer accurately?

Compared to mysterious electrode life, thermal analyzer meters can be used for years or even decades. However, the late thermal analyzer operation is very simple, requiring the operator to calibrate many times, and may need to manually adjust the value displayed during calibration. Today's thermal analyzers are increasingly diversified, and their methods of use vary widely. However, most have completed a simple calibration operation.
