About This Product
In physiology and health science teaching, the thermometer shows how a liquid expands along a narrow capillary and how a constriction holds the column at its highest point until it is shaken down. Students practise reading the magnified scale against the marked 37°C line.
Frequently Asked Questions
How is the reading reset on this clinical thermometer?
The column is held by a constriction in the capillary and is reset by shaking the thermometer down.
