美國Shortridge Instruments數據萬用表,ADM-880C萬用表
ADM系列空氣數據萬用表可用作手持式便攜式儀表，用于測量空氣速度、壓力和溫度。這些儀表也可用于獲得8400 FlowHood套件的直接空氣流量讀數。任何型號的儀表都可以在需要時升級為具有更大功能的型號。
ADM-880C、ADM-870C和ADM-860C型提供存儲讀數的存儲器（分別為2000、200和100個讀數），以及用于將存儲的讀數串行輸出到打印機或計算機的RS232通信端口。ADM-880C為數據記錄和故障排除應用程序提供了特殊功能。
ADM-850L型是AirData萬用表的簡化版本。請注意，ADM系列AirData萬用表套件中的任何一個都可以與8400 FlowHood套件一起購買，也可以不購買。
