Note on The Correction of Reversing Thermometers
Corrections have to be applied to the readings of protected and
unprotected reversing thermometers because they are read at a temp
erature that differs from that at the time of reversal. In deriving
these corrections it is generally assumed that Feruglio’s (1912) equa
tion [(5) below] is exact. It is shown here that Feruglio’s equation
is not quite exact, but a close approximation. From this equation
practical formulae, equations (6) and (S) below, can be derived very
simply without further sacrifice of accuracy.
