Question

• A. mercury based only
• B. digital only
• C. either mercury based or digital
• D. coloured alcohol based

Answer 1

The correct option is C either mercury based or digital

Clinical thermometers are small medical thermometers used for measuring a person's temperature. Mercury-based clinical thermometers have been considered the most accurate liquid-filled thermometer type. However, Mercury is a poisonous metal. Therefore a safer and an accurate alternative option, is to use digital clinical thermometers. Thus, both mercury and digital clinical thermometers are used.
