Electric contact thermometer showing the value of the basic allowable error
From 100 ℃ ~ 200 ℃ error ± 3 ℃
From 0 ℃ ~ 100 ℃ error of ± 2 ℃
From 0 ℃ ~ 50 ℃ error of ± 2 ℃
Instruction manual:
1, the thermometer insertion depth must be measured, which can
3, supporting the use of electronic relays thermometer required by current and voltage the smaller the longer service life.
4, mercury disconnect repair:
a, the mercury bulb in a cool bath (solid carbon dioxide) so disconnected part incorporated in the mercury ball.
b, the mercury bulb slowly heated to disconnect the upper end of the liquid column raised security bubble combination (note when safe operation can not be filled with mercury bulbs to prevent bulb burst).
