Analysis of the causes of poor repeatability in moisture analyzer
2021-09-01 11:06:10
1. The sample is not uniform. For example they have different ingredients. The more uneven the sample, the more samples are needed to get better repeatability results.
2. The drying time selected is too short. Extend the drying time or choose the appropriate shutdown mode "weight loss per unit time".
3. The sample is not completely dry (eg due to surface crust). Try mixing quartz sand for drying.
4. The selected temperature is too high or the sample is oxidized. Reduce the drying temperature.
5. The sample boils and continually splashes from the moisture meter to change the temperature. Please clean the protective glass.
6. When the protective glass is eroded, the heating amount cannot be fully exerted. Please clean the protective glass.
7. The temperature sensor is contaminated or damaged. Please clean the temperature sensor.
8. The external environment is unstable (vibration, etc.).
9. The console is not stable. Please apply a stable console.
