ng style="mso-bidi-font-weight: normal;">KX-1ng>ng style="mso-bidi-font-weight: normal;">型電阻式真空計主要用在低中真空范圍內進行內進行真空測量和指示的一種常用真空機表,可以對冶金、電子、化工、電真空、輕紡工業等需要測量真空的地方都可以使用。ng>ng style="mso-bidi-font-weight: normal;">ng>
ng style="mso-bidi-font-weight: normal;">三.使用原理:ng>ng style="mso-bidi-font-weight: normal;">ng>
ng style="mso-bidi-font-weight: normal;">KX-1ng>ng style="mso-bidi-font-weight: normal;">型電阻式真空計的傳感器是特制的皮拉尼式傳感器,內為鍍金鎢絲,陶瓷金屬密封,金屬外殼,這樣有利於機表的穩定性,抗乾擾性,長的壽命和牢固性。ng>ng style="mso-bidi-font-weight: normal;">ng>
ng style="mso-bidi-font-weight: normal;">該機表結構簡單,體積小,操作簡單,可以直接讀出真空數值,是一種比較理想的真空測量機器。ng>ng style="mso-bidi-font-weight: normal;">ng>
