More meaningful comparisons can be made by comparing water loss from the potometer with that from an atmometer ( an apparatus used to measure the rate of evaporation from a porous pot or other nonliving wet surface ) , which allows uncontrolled evaporation 更有意義的是,可以比較蒸騰計的失水與蒸發計(通過有孔小罐或者潮濕表面來測量蒸發速率的儀器)的失水間的區別。

This is normally closely related to the rate of water loss by transpiration , and the potometer can be used to compare transpiration rates under different conditions 通常與由于蒸騰作用而喪失水分的速率緊密相關,蒸騰計可被用于在不同條件下進行蒸騰速率的比較。

Potometer an apparantus for measuring the rate of water uptake by a cut shoot or whole plant 蒸騰計:通過莖切段或整個植物體來測量水分吸收速率的儀器。
