What are the advantages of the bimetallic thermometer?

As people living standard enhancement, is also more and more high to the requirement of using the thermometer, concrete embodiment in appearance, degree of accuracy, cost-effective, portable, etc. And the upgrading of the thermometer is level. All busy urbanite, stressing efficiency, also for thermometer, the beginning is the glass rod, then, the panel instructions, think reading is more convenient than the glass rod, then a digital display, reading up more convenient than mechanical display. Even so, the machinery of the bimetallic thermometer instructions, the market is still not small, why people still continue to use the bimetallic thermometer? This was from the advantages of the bimetallic thermometer. Bimetallic thermometer mainly has the advantages of the following three aspects: 1. High precision. When measuring temperature, bimetallic temperature heat pipe need to insert into the liquid being measured, the heat source is more stable, more accurate measurement of numerical also; 2. High cost performance. Compared with similar performance thermocouple, bimetallic thermometer cost-effective; 3. Use a wider range. Compared with ordinary digital display thermometer, the use of bimetallic temperature is wider.
