sbd-2 mcleod vacuum gauge
概 述：麥氏真空計是根據(jù)波義耳定律設計的一種真空測量儀器.
general description: mcleod vacuum gauge is a vacuum measuringdevice designed based on boyle law.
注意事項 ：
precautions:
1、真空計必須輕拿輕放，避免強烈震動。
the vacuum gauge must be handled carefully and prevented fromfierce vibration.
2、搬運過程中切勿倒置，避免水銀溢出。
do not place it upside down during transportation to avoid overflowof mercury.
3、測量時務必使真空度穩(wěn)定后方可測試。
make sure that testing can be conducted only after vacuum degree ismade stable during measuring.
4、每次測量后必須使水銀全部回到真空計底部。
all mercury must return to the bottom of the vacuum gauge aftereach measurement.
5、本真空計只能測試非凝性氣體。
this vacuum gauge can be used to test non-condensable gasesonly.
