Between MERCURY THERMOMETER and
ALCOHOL THERMOMETER from the ADVANTAGES
and DISADVANTAGES are :
ADVANTAGES :
1.CHEAP
2.DURABLE
3.ACCURATE
4.EASILY CALIBRATE
DISADVANTAGES :1.Display is harder to read2.does not work below -39ºC (Hg freezing pount)3.cannot be used for thermograph4.slow response5.Fragile6.mercury vapour is poisonous
ADVANTAGES :
1.lower freezing point (-114
ºC) 2.larger coefficient of
expansion
3.less hazardous
DISADVANTAGES :1.less durable (alcohol evaporates) 2.alcohol can polymerise3.fluid loss by evaporation hard to avoid4.lower boiling point (60 ºC)

DEFINITION Of CLINICAL THERMOMETER
thermometer used to measure body temperature, especially a small glass thermometer designed with a narrowing above the bulb so that the mercury column stays in position when the instrument is removed from the body.
A thermometer having a graduated glass tube with a bulb containing a liquid, typically mercury or colored alcohol, that expands and rises in the tube as the temperature increases.
