Temperature major through a thermometer, one is contact type thermometer another one non contact type.Non contact type thermometer known as laser thermometer. With non contact type thermometer or leaser thermometer you will read out temperature from a particular long distance without contact the particular point which temperature want to know.Contact type thermometers are glass type thermometers, analogue or digital read out type. Digital thermometer and analogue dial read out type thermometer have a sensor and that sensors must be to touch hot or cold point to read the temperature.Best use of contact type thermometer is uses full in a closed area. To know grill temperature of a slip Air Condition best use nonContact thermometer to read exact temperature.
The thermometer would melt
