Description

大气压测量器
本实用新型是一种改进的托里拆利实法仪器。
目前,中学课堂上仍然应用托里拆利实验器进行大气压测量,实验过程中不仅向托里拆利管中注入水银费时费力,而且实验者直接接触水银对人体会产生一定的毒害作用。
本实用新型的目的是提供一种安全、无毒、快速、准确有大气压强测量器。
本实用新型包括支架、容封式盛汞容器,其特征在于支架上用固定件固定有长颈漏斗及容封式盛汞容器,盛汞容器顶部插入有长颈漏斗及进气开关,漏斗颈斗处装一容闭开关。
漏斗颈长900mm,内径1mm。
附图为本实用新型结构示意图。
图中:1支架  2长颈漏斗  3漏斗开关  4固定件  5进气开关  6盛汞容器实验  时,打开漏斗开关和进气开关,用气囊或气筒通过进气开关对容器中的水银加压,水银便沿漏斗颈上升到漏斗中,关闭漏斗开关,水银柱下降静止时,测量水银柱的高度便是当地的大气压强值,测量结束关闭进气开关。
本实用新型结构简单,操作安全方便,测量准确,快速。
