How To Use Glass Thermometer

If you buy a glass thermometer, then you must learn to use it correctly. Because the use of glass thermometers requires us to be very careful. The following is a brief introduction to how to use the glass thermometer!

Before use, we must first observe the range of the thermometer, select a suitable thermometer that has been calibrated internally, and recognize its minimum scale for accurate reading.

Before measuring the temperature, the level of the measured temperature should be estimated to prevent the measured temperature from being too high. The liquid in the thermometer will swell the thermometer.

When measuring the temperature, the glass bulb of the thermometer should be in full contact with the measured object.

The reading of the thermometer is stable after reading.

When reading, the glass bubble of the thermometer should be left in the liquid to be measured, and the line of sight should be level with the liquid level in the capillary. If it is a mercury thermometer, the convex surface shall prevail. If it is an alcohol or kerosene thermometer, the bottom of the concave surface shall prevail when observing.
