Milk thermometer is a device used to gauge milk's temperature. The temperature is measured using the thermometer's scale once it has been put into the milk. In order to guarantee that milk is heated to the proper temperature for pasteurisation, the dairy industry uses milk thermometers. It is designed for testing the temperature of calf milk and wash water. Milk thermometer is frequently used to assess the temperature of milk before feeding, the temperature of wash water, and the temperature of water in a water bath to thaw frozen colostrum.
