 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 read 2.does not work below -39ºC (Hg freezing pount) 3.cannot be used for thermograph 4.slow response 5.Fragile 6.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 polymerise 3.fluid loss by evaporation hard to avoid 4.lower boiling point (60 ºC)

BASED On Discoverer : 1. CELCIUS Thermometer 2. REAMUR Thermometer 3. FAHRENHEIT Thermometer 4. KELVIN Thermometer SPECIAL Thermometer : 1. CLINICAL Thermometer 2. WALL Thermometer 3. MAXIMUM and MINIMUM Thermometer

OTHERS Thermometer : 1. GAS Thermometer 2. PLATINUM Thermometer 3. THERMISTOR Thermometer 4. THERMOKOPEL Thermometer 5. PYROMETER Thermometer

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. bulb
