（1） Purpose:

The WSS-501F bimetallic thermometer is an industrial instrument suitable for on-site detection of medium and low temperatures. Can be used to directly measure the temperature of gases, liquids, and vapors. This thermometer has the advantages of no mercury hazard, easy reading, sensitive response, and strong vibration resistance. It can replace industrial glass mercury thermometers and is widely used in industrial and scientific research departments. It can be used for temperature measurement of most corrosive media and gases. This instrument belongs to the category of vibration resistant mechanical instruments.
