To determine how hot an electric stove top burner is without burning something, you can follow these steps:
Visual Indicators: Some modern electric stoves have visual indicators near the control knobs or on the display panel that show the heat level of each burner. These indicators typically use numbers or symbols to represent different heat settings (low to high). Check your stove's user manual to see if it provides information about the visual indicators.
Use an Infrared Thermometer: An infrared thermometer is a non-contact device that can measure the temperature of a surface without making physical contact. Point the infrared thermometer at the surface of the stove burner while it's on, and it will give you an instant reading of the temperature.
Hand Test (Caution): Caution should be exercised when using this method, and it's not recommended if you are sensitive to heat or unsure about the temperature. Turn on the burner to your desired setting (e.g., medium) and hold your hand about 6 inches above the burner surface. Please pay attention to the sensation of heat and how quickly you feel it. You can use this as a rough estimate of the temperature.
Use a Temperature Indicator Strip: Temperature indicator strips are adhesive strips that change color at specific temperatures. They can be applied to the surface of the stove burner, and the color change will indicate the approximate temperature reached.
Test with a Drop of Water (Caution): This method is not highly accurate and should be used with caution. Sprinkle a few drops of water on the burner surface when it's on, and observe how the water behaves. If it sizzles and evaporates immediately, the burner is very hot. If it forms droplets that dance around and take some time to evaporate, the burner is at a lower temperature.
Remember that these methods provide only rough estimates of the temperature and should not be relied upon for precise measurements. If you need precise temperature control for cooking, it's best to use a thermometer or follow the temperature settings on the stove if available. Always practice caution when dealing with hot surfaces, and never touch the burner directly with your hand or any sensitive object to avoid burns or injuries.
