Do you know about bimetallic thermometer error range?

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 precision grade based on its 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. Example: 1. Level 5 and 1. Level 0 respectively under normal use, the the permissible error of the thermometer was range & plusmn; 1. 5 and & plusmn; 1. 0%. Bimetallic thermometer with adjustable screw for all of the bimetallic thermometer precision fine-tuning; The screw on the reverse of the pan for field calibration; This feature can ensure maximum precision at the specified temperature range. Accuracy, in strict accordance with the ASME B40. 200 - 2008 standards.
