Bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. Bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. Bimetallic thermometer is applied in chemical and petrochemical industry; Power engineering; Field of food. Construction machinery and general factory. How to choose the bimetallic thermometer precision grade? Under the condition of normal use, the instrument the accuracy of the measurement results of the accuracy of the instrument, traditionally known as precision instrument accuracy. Using precision grades of bimetallic thermometer is 1. 0 and 1. 5, 2, 2. 5, 4. Bimetallic thermometer precision grade is it permissible error of the dial scale value by it's percentage, its accuracy level the greater the number of permissible error of dial scale limit value is larger. Range, the greater the same precision level, it measured the absolute value of the temperature the greater the margin of error. For bimetallic thermometer precision grade is 1. Level 5 and 1. Level 0, respectively under normal use, the permissible error of the thermometer was the range & plusmn; 1. 5 and & plusmn; 1. 0%.
