The use of glass rod thermometer

When we were in the use of glass rod thermometer have what need to be aware of? How is ability with accurate readings, small make up today will discuss with you. 1. Observe its range & ndash; — Can measure temperature range, if the estimate for the temperature beyond the highest temperature of it can be measured, or less than the minimum temperature, it can be in with a range of appropriate thermometers, otherwise will likely liquid in the thermometer thermometer burst, or measured temperature value. 2. Identify the smallest scale value of it, in order to use it can be read quickly temperature measurement. 3. All the glass bulb thermometer into the liquid being measured, don't touch the bottom of the container or the container wall. 4. Glass bulb thermometer immersed in liquid after being tested to wait for a while, after waiting for thermometer readings stable reading again. 5. When reading glass bulb want to remain in the liquid being measured, the line of sight and flat on the thermometer liquid column in the table above face. The use of the thermometer method one: 1, before measurement, observations to use thermometer, understand its range ( Measuring range), And dividing value ( Each small case the corresponding temperature value) ； 2, to make the glass bulb of the thermometer measurement with good contact with the liquid to be tested, To be submerged in the liquid being measured) ； 3, to stay stable readings after reading; 4, when reading the thermometer glass bubble is measured in the liquid to stay, can't take readings. Method 2:1. Before the measurement to estimate the temperature of the liquid being tested; 2. According to estimate the temperature of the range of suitable thermometer. 3. The glass bulb of the thermometer should be completely submerged in the liquid under test, but don't run into the bottom of the container and the container wall. 4. Glass bubble is completely submerged in the liquid under test to wait for a while. Such as its stable readings before reading. 5. Reading, glass bulb to remain in the liquid is measured. 6. The line of sight to the liquid column in the table above physiognomy thermometer. Measurement results are correctly recorded Numbers and units. By understanding the use of the glass rod thermometer, we according to standard operation at the operation, so we can't achieve accurate readings.
