Glass Thermometer Fill with Red Spirit 200°C Celsius

Using a thermometer is a reliable way to ensure safety and to determine the “doneness” of most foods. To be safe, a product must be cooked to temperature high enough to destroy any harmful bacteria that may have been in the food. Glass thermometers are designed for food or any DIY projects. As the internal temperature of the food increases, the colored liquid inside the thermometer expands and rises to indicate the temperature on a scale.
