Advantages

• It is suitable to measure low temperatures because of its freezing point is low.
• It is less toxic than mercury thermometer and hence high on safety factor for human and environment.
• It has a greater value of temperature coefficient of expansion than a mercury thermometer.
• Alcohol Thermometer is less expensive than a mercury thermometer.

Disadvantages

• It is less durable because alcohol evaporates faster than mercury.
• It cannot measure high temperature because of a low boiling point.
• It wets the walls of the thermometer, which can adversely impact the accuracy of readings.
