Problems and solutions in using moisture online measuring instrument
- 2020-04-02-

The on-line moisture measuring instrument uses the principle of Calfusci micro-coulometric titration analysis. The titration process is detected by double platinum electrodes. The single-chip microcomputer controls the measurement and electrolysis and data processing, and automatically prints the parameters and measurement results. This instrument has the characteristics of active baseline correction, blank compensation, good stability, accurate results, easy operation, fast analysis speed, good repeatability of analysis data, and easy device installation. It can be widely used in all industries that require rapid moisture determination.


However, in the process of using the online moisture measuring instrument, it will also present some problems, and then lead to production or experimental errors. What are the common problems in the use of the online moisture measuring instrument? And how to solve it?


First, the crash problem: when the instrument is opened, it cannot be turned on normally. In this case, the instrument must first be checked to determine whether the instrument is now damaged. If there is no damage to the instrument, check the operating conditions, such as whether the power cord is connected, whether the voltage is too high or too low, whether the fuse is now blown, or the external ambient temperature is too low. Second, poor repeatability: Generally speaking, the instrument's own operating table is unstable, and the temperature sensor may be contaminated or damaged, which will lead to poor measurement repeatability. At this time, only the stable operating table is required, and the temperature sensor may be cleaned or replaced. And the environment and settings will also affect the repeatability, the external environment is unstable, the selected temperature is too high or the sample is oxidized, the sampling volume is not standard, the operation method is not standard, etc. may be the cause of the problem. At this time, the drying temperature can be reduced and extended Time to solve the problem.


In addition to the above common problems, the use of the online moisture measuring instrument is also accompanied by various problems. When encountering problems, you need to calmly consider and determine the cause of the problem before you can take the right medicine.
