The range of each thermometer.
(1) -38,C to +2,C
(2) -8,C to +32,C
(3) +25,C to +55,C
(4) +50,C to +80,C
(5) +75,C to 105,C
(6) +90,C to 155,C
(7) +145,C to +205,C
(8) +195,C to +305,C
NOTE: There are other sets of thermometers listed in the the supply catalogs, however,
this set is representative of the others.
c. The third type of secondary reference thermometer is the resistance thermometer. The
principle of operation of the resistance thermometer has been discussed before. Here we
have a platinum resistance thermometer and the Mueller Bridge, model E-1003.
