A digital thermometer is a device that uses electronic sensors to measure temperature. It displays the temperature as a number on a screen. Think of it like a mini-computer that tells you how hot or cold something is!
An analog thermometer, often the glass kind, uses a liquid (usually alcohol or mercury) that expands or contracts with temperature changes. You read the temperature by looking at where the liquid stops on a scale.
| Feature | Digital Thermometer | Analog Thermometer |
|---|---|---|
| How it Works | Electronic sensor | Liquid expansion/contraction |
| Display | Digital number on screen | Liquid level on a scale |
| Accuracy | Generally more accurate | Can be less accurate if not read carefully |
| Speed | Faster reading | Slower reading |
| Battery | Requires battery | No battery needed |
| Safety | Safer (no glass or mercury) | Can be fragile and contain mercury (older models) |
