Sper Scientific 736680 Min-Max Thermometer With Magnet User Manual
Page 2

Operation: Use the magnet to 
bring the blue floats to rest on the 
top of the mercury columns on both 
the right and left sides. The starting 
temperature for each float should 
be the same. Note: the scales on 
the left side are reversed from the 
one on the right. 
 
As the temperature changes the 
floats will be moved by the mercury 
columns. The floats will stick at the 
highest and lowest temperatures 
until reset. 
 
The bottom of the float registers the 
maximum temperature on the right 
side and the minimum temperature 
on the left. To reset the floats use 
the magnet to move them to the top 
of the mercury columns. 
 
Notes: The mercury is packed in a 
clear liquid. If air bubbles form in the 
liquid, place the thermometer upright 
in the sun, and let the bubbles rise to 
the top. Or, see instructions for First 
Use. Never put the thermometer into 
an oven. 
 
Breakage: Do not return a broken 
thermometer. Dispose of mercury 
according to your local waste-
management guidelines. Do not 
touch Mercury - it is toxic!
