| 2. | The temperature range of the clinical thermometer is 35°C to 42°C. | The temperature range of the laboratory thermometer (simple thermometer) is -10°C to 110°C |
| 3. | The clinical thermometer has a constriction or kink to hold the thermometric liquid. | A simple thermometer doesn't have constriction or kink. |
