People often use the thermometer, can know the thermometer used in different places have different methods of use, because if the wrong way, may lead to different problems, today to introduce specific laboratory thermometer using method. ( A) In a thermometer is used to measure the liquid temperature, the correct method is as follows: 1. Hand the upper end of the thermometer, glass thermometer bubble all immersed in the liquid being measured, don't touch the bottom of the container or the container wall. 2. Glass bulb thermometer immersed in liquid after being tested to wait for a moment, after waiting for thermometer readings stable reading again. 3.

( One end of the thermometer with your hands, can avoid the hand of the temperature of the liquid in the table. If the glass bulb thermometer run into the bottom of container or wall, determination is not water temperature; Within the range if the thermometer liquid column to stop lifting is reading, or out of the water when reading, the reading is not the real temperature of water. ) Note: don't jilt before measuring temperature ( 2) Temporary 1 when the indoor and outdoor temperature is measured. The upper end of the thermometer with your hands, such as liquid column within the thermometer when they stop lifting and readings; 2. Readings, the line of sight to also want to and the hydraulic pillars of the thermometer at flat; 3. If long-term measure outdoor temperature, to hang the thermometer in the shaded ventilated place. Laboratory when use, should pay special attention to the use of the laboratory thermometer, this will bring us convenient.
