What are the considerations of laboratory thermometer use?

1, the thermometer can't contact the container edge. ( Thermometer and containers are glass material, it is easy to damage. ) 2, the glass bulb of the thermometer ( At the top) Can't fall to the bottom of the container. ( Easy to damage) 3, the glass bulb of the thermometer ( At the top) To fully immersed in a liquid. ( If you don't dip, the thermometer can't feel the temperature of the liquid) 4, when reading the line of sight in parallel with the scale of the thermometer, cannot look down and look up. ( Looking down or look up readings inaccurate) 5, when reading, can't read the thermometer from the liquid out. ( Take out the thermometer from the liquid, thermometer surrounding temperature changes, affecting the temperature meter readings) 6, the measured temperature cannot exceed the scope of the measuring range of the thermometer. ( If the measured temperature is lower than the lowest temperature of the thermometer, is unable to display the data. If higher than the highest temperature of the thermometer, the thermometer will be burst) Conclusion: common attention see above the reading of the thermometer. Thermometer readings can leave the human body.
