A minimum thermometer is used to measure the lowest temperature reached since last reset. It contains a liquid of low density, such as alcohol, which expands as temperature decreases, moving the liquid up the tube. Once the temperature rises, a constriction in the tube prevents the liquid from returning to its original position, keeping the maximum measurement until reset. The other options (bimetal strip and thermistor) use different principles to measure temperature and do not necessarily contain a liquid of low density. Maximun thermometer also uses a different mechanism compared to minimum thermometer.
