What aspects determine the advantages and disadvantages of industrial pH meters?
The accuracy of industrial pH meters: Without accuracy, industrial pH meters have no practical value. The method of judgment is to use a high-precision industrial pH meter or high-precision standard liquid calibration.
The stability of industrial pH meters: Unstable industrial pH meters are difficult to read and ensure accuracy. Stability is manifested in two aspects: first, the stability of a single industrial pH meter. The same industrial pH meter can be placed in a stable solution for a long time to see if the value changes and the magnitude of the change; On the other hand, for the stability of multiple industrial pH meters, it is difficult to ensure the accuracy and stability of each industrial pH meter if several calibrated industrial pH meters of the same model are placed in the same stable solution to see if the readings are consistent and how much error there is. If stability cannot be guaranteed between several industrial pH meters of the same model, it will be difficult to ensure the accuracy and stability of each industrial pH meter.
The adjustment of common errors in industrial pH meters: Temperature is a significant factor that causes errors in industrial pH meters. The presence or absence of temperature probes and the sensitivity of temperature probes also affect the use of industrial pH meters.
Industrial pH meters are easy to operate and have a beautiful interface: users can easily judge this aspect. Some old industrial pH meters use analog switches, which makes calibration difficult, small changes are not easy to detect, and can easily lead to fatal system errors. Considering cost and technology reasons, there are still many industrial pH meters that use LED digital tubes, which lack rich display content. Of course, some manufacturers have made up for this disadvantage through certain means. At present, the commonly used interface for convenient operation is generally LCD display+keyboard style operation.
Advantages and disadvantages of industrial pH meter electrodes: The performance of industrial pH meter electrodes directly affects some technical indicators of industrial pH meters, and even superior industrial pH meters equipped with inferior pH electrodes are of no use.
The precision of industrial pH meters: In recent years, more and more customers have begun to pay attention to the safety of industrial pH meters. well-designed industrial pH meters using lower * * voltage inputs can greatly improve safety performance.
