The product is composed of a glass thermometer, a scale brand and a protective sleeve. Temperature sensitive liquid: red, packed in a warm bulb and a capillary tube. Scale plate: made of thick 0.5mm aluminum plate, scale plate length 500mm, the scale of the line has two kinds of temperature indication, Celsius temperature (symbol?) and thermodynamic temperature (symbol?). Warm bubble: About 135mm, located in the lower end of the thermometer. Capillary: installed in the scale board, the capillary cross-section of the triangle, when the positive observation from the front, there is amplification. Scale range: 0 ~ 100? Scale range: 0 ~ 100 ?, thermodynamic scale of 273 ~ 373K. Each 1o line length is 4mm. Each 1o for the short term, each 5O for the middle line, each 10o for the long term. Showing the value of tolerance ±1?.
