Troubleshooting problems during the operation of the moisture analyzer
Crash problem: When the instrument is turned on, it cannot be turned on normally. When encountering this situation, the instrument must be checked first to determine whether the instrument has been damaged. If there is no damage around the instrument, then it is necessary to check the conditions of use, such as whether the power cord is connected, whether the voltage is too high or too low, whether the fuse has blown, or the external environment temperature is too low, etc. Second, poor repeatability: Generally speaking, if the operating table of the instrument itself is not stable, or the temperature sensor is polluted or damaged, the repeatability of the measurement will be poor. At this time, it is only necessary to stabilize the operating table and clean or replace the temperature sensor. And the environment and settings will also affect the repeatability. The external environment is unstable, the selected temperature is too high or the sample, 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 and drying time can be reduced. Wait to fix the problem.
There are currently two main types of moisture analyzers on the market:
1. Chemical analysis method Moisture meter, as the name implies, the chemical analysis method is that the substance undergoes a qualitative change, that is, a new substance is generated, and this type is mainly used for trace moisture determination.
2. Physical analysis method moisture meter, this kind of relatively simple structure does not require such complicated experiments. It can evaporate free water by heating to a high temperature. one-third.
