The days maximum and
the night’s minimum, temperature can be determined on these
instruments at every time or be read afterwards as conveniently as you
read every raise and fall of temperature indicated on it. How they work:
First push on the button and replace the blue signals in the tube down
to the mercury column in either tube arm.By.the original execution of
the minima—maxima—thermometer withoutfp~1sh—buttotI~ the enclosed
magnet reports the signalWhen temperature raises or falls, the signals
will be pushed upwards and will rest in the capillary in a free position,.so
that even at some later time you may easily read from the basis of the
signals the maximum and minimum temperatures of the last period.
In case
of air—bubbles in the tube connect first of all the marks with the
mercury column, which can be achieved by shaking the thermometer so that
the air—bubbles can pass the marks.
Then put
the thermometer on the radiator(not on a stove ).Due to the heat the air—bubbles
are then pressed upwards and can escape. Should the mercury column have
separated possibly in transport, do some shaking in a simildr and
vigourolis manner as ç’ou do with clinical thermometers and mercury
will join again.
If one or both marks
are not visible handle the instrument in the same way by shaking while
pushing the button.
