7250LP型低壓數字壓力校準器是7250 系列中的一個特殊型號，專門設計用於滿足對以下儀器校準的性能要求：低壓壓力傳感器、壓力變送器、機械式壓力計、便攜式校準器及其插件模塊。
為適應雙向壓力設備，7250LP 在正表壓模式和負表壓模式下均可工作。
以下三種不同的範圍組合可供您選擇，單台儀器中可包含兩個範圍：
- 10 inH2O 和30 inH2O（25 和75mbar）
- 20 inH2O 和60 inH2O（50 和150mbar）
- 35 inH2O 和100 inH2O（87 和250 mbar）
7250LP 在滿量程的10% 至100% 內可提供讀數0.005% 的精度。例如，測量30 至3 inH2O（75 至7.5 mbar）的壓力時，10/30 inH2O 7250LP 可提供讀數0.005% 的精度。範圍的增大和縮小變化均為自動操作，無需操作人員干預。由於7250LP 採用了差壓傳感器，因此，可將參考端口連接到測試系統的低端，以消除因大氣壓波動引起的壓力干擾。
