How to solve the problem of poor repeatability in the process of measurement of halogen moisture meter?

   1, the sample is not uniform, for example, they have different components, the more uneven the sample is, the more samples are needed to obtain better reproducible results.

　　2、The selected drying time is too short, extend the drying time or select the appropriate closing mode “weight loss per unit time”.
　　3, the sample is not * drying, for example: due to surface crusting, try to mix quartz sand for drying.
　　4、Select the temperature too or sample oxidation, reduce the drying temperature.
　　5、When the protective glass is fouled, the heating heat can not * play, please clean the protective glass.
　　6、The temperature sensor is contaminated or damaged, please clean the temperature sensor.
　　7、The operating table of halogen moisture meter is not stable, please apply a stable operating table.
　　8、External environment is unstable (vibration, etc.).
