2000系列 微差壓表
精度為±2%，能現(xiàn)場指示正壓，負壓或差壓
2000系列 微差壓表有81種量程范圍可供選擇，精度為2%。采用了無磨損的機芯，結(jié)構(gòu)簡單可靠，可快速靈敏地指示氣體的微小正壓，負壓或差壓，它還具備防震和過壓保護的功能。Magnehelic®微差壓表的價格經(jīng)濟合理，使用方便，避免了測量中的液體差壓計的液體蒸發(fā)，結(jié)凍和必須水平矯正等問題。
2000系列 Magnehelic®微差壓表被廣泛應用于監(jiān)測風機出口靜壓，過濾器阻力，測量風速，通風狀態(tài)，測量孔板兩邊的差壓，還用于吹泡液位測量系統(tǒng)監(jiān)測液位，監(jiān)測氣體，空氣的混合控制比例，在醫(yī)療設(shè)備和裝置中監(jiān)測血壓，和呼吸壓力等。
注：可以用于氫氣，但在訂購時須選用Buna-N丁氰橡膠隔膜，工作壓力在35psi。
