The micro moisture analyzer often encounters the problem of poor repeatability in operation, which will affect the measurement effect. This is often caused by improper operation of the measurement method. During the measurement process, pay attention to the sampling of samples, and select samples with humidity within a reasonable range to stop the measurement. Next, we will analyze the reason for poor measurement repeatability. The sample is not monotonous (for example, due to surface crusting). Check that the mixed quartz sand stops monotonous. The sample splashes from time to time and then affects the weighing of the micro moisture analyzer. Please lower the inspection temperature. The samples are uneven. For example, they have different ingredients. The more uneven the samples are, the more samples are required to achieve a better repeatability.
The selected temperature is too high or the sample is oxidized. Falling monotone temperature. Contamination of maintenance glass will lead to the failure of heating capacity, and the splash of samples will change the temperature from time to time. At this time, the maintenance glass can be cleaned. The operating platform of the micro moisture analyzer is unstable. Please use a stable console. The temperature sensor is contaminated or damaged. Please clean the temperature sensor. When the heater is polluted and corroded, the heating capacity cannot be used. Please clean the heater surface of the micro moisture tester.
The moisture content lost by the sample will flash when the micro moisture tester is continuously measuring, so we just need to stop the monotonous disposal of the measured items, choose the correct operation method, ensure the average and stability of the sample, record the measurement effect in time, and remember to re adjust when stopping the measurement again
