Clinical thermometers are meant for measuring human body temperature between 35-42°C, while laboratory thermometers can measure a wider range from -10-110°C for uses like checking boiling points. Clinical thermometers were invented in the 1830s by Sir Thomas Clifford Allbutt and first manufactured in 1867, while laboratory thermometers were invented earlier in 1612 by Santorio Santorini and could measure a broader temperature range than clinical thermometers. The key difference is that clinical thermometers are designed specifically for human body temperature measurement whereas laboratory thermometers have a greater temperature measurement range for scientific and laboratory uses.

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thus these thermometers have been
replaced by digital thermometers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.

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.
