Digital thermometer work environment conditions

The thermometer is a measure of measuring temperature, can know the temperature accurately, for family, saddled a mercury thermometer to measure body temperature is a must, especially children, always concerned about the health of children. And industry, like bimetallic thermometer, winding thermometer is right choice, steel-making iron-smelting industry are made. In addition to the above several small make up said, there are many other thermometer, digital is the thermometer is one of them. Digital thermometer in 15 ℃ ~ ℃, relative humidity of 80% or less under the environmental conditions of the calibration. Digital thermometer, power is supplied by batteries thermometer calibration voltage should be in the scope of works; Using thermocouple temperature sensor thermometer should be far away from heat source, the environment temperature should be relatively stable.
