6. What is a
Clinical
Thermoter
 Clinical thermometers are meant for
clinical purposes. It is developed for
measuring the human body
temperature. It is a long narrow glass
tube with a bulb containing mercury at
the end. The normal human body
temperature is 37˚C; which can fluctuate
between the ranges 35˚C to 42˚C.
Hence, the clinical thermometers have
the range 35˚C to 42˚C. The level of
mercury tells our body temperature in
˚C. Since mercury is a toxic element,
thus these thermometers have been
replaced by digital thermometers
nowadays.

7. Who and when invented the Clinical
Thermoter
1836–1925
Sir Thomas Clifford Allbutt (1836–1925)
was a celebrated British physician. He
spent 20 years working in Leeds during
which time he devised the small clinical
thermometer.
1867
. A local company, Harvey and Reynolds,
first manufactured this special
thermometer in 1867, followed by
Thackeray in London.

Thermometer

10. What is a
Laboratory
Thermometer
 Since clinical thermometers can’t be
used to measure temperature other than
the human body, we need a special type
of thermometers for other purposes. A
laboratory thermometer, which is
colloquially known as the lab
thermometer, is used for measuring
temperatures other than the human
body temperature. It ranges from -10˚C
to 110˚C. Laboratory thermometers are
designed for lab purposes such as
checking boiling point, freezing point, or
temperature of other substances. You
can use a laboratory thermometer for
checking the temperature of a solvent
but not a clinical one.

11. Who and when invented the Clinical
Thermometer
1561–1636
Santorio Santorini (Sanctorius, 1561-
1636) is commonly credited with the
invention of the first Laboratory
thermometer
1612
Santorio Santorini invented the
first thermometer in 1612. It was
invented in Italy.
