What aspects determine the advantages and disadvantages of industrial pH meters?
Accuracy of industrial pH meter: An industrial pH meter without accuracy has no use value. The way to judge is to use a high-precision industrial pH meter or a high-precision standard solution for calibration.
Stability of industrial pH meter: It is difficult to read an unstable industrial pH meter and ensure accuracy. The stability is reflected in two aspects: First, the stability of a single industrial pH meter. The same industrial pH meter can be left for a long time. In the stable solution, see whether the value changes and the extent of the change; on the other hand, for the stability of multiple industrial pH meters, put several calibrated industrial pH meters of the same model into the same stable solution to see if the readings are consistent and what is the error? , if the 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.
Adjustment of common errors in industrial pH meters: Temperature is the most obvious factor causing errors in industrial pH meters. The presence or absence of a temperature probe and the sensitivity of the temperature probe also affect the use of industrial pH meters.
Industrial pH meters are easy to operate and have beautiful interfaces: it is relatively easy for users to judge this aspect. Some old-style 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. In addition, taking into account cost and technical reasons, there are still many industrial pH meters that use LED digital tubes, and the display content is not rich enough. Of course, some manufacturers have made up for this shortcoming through certain channels. At present, the most commonly used interface for convenient operation is LCD liquid crystal display + keyboard 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. No matter how superior an industrial pH meter is equipped with inferior pH electrodes, it will not help.
