美国Shortridge Instruments数据万用表,ADM-880C万用表
ADM系列空气数据万用表可用作手持式便携式仪表，用于测量空气速度、压力和温度。这些仪表也可用于获得8400 FlowHood套件的直接空气流量读数。任何型号的仪表都可以在需要时升级为具有更大功能的型号。
ADM-880C、ADM-870C和ADM-860C型提供存储读数的存储器（分别为2000、200和100个读数），以及用于将存储的读数串行输出到打印机或计算机的RS232通信端口。ADM-880C为数据记录和故障排除应用程序提供了特殊功能。
ADM-850L型是AirData万用表的简化版本。请注意，ADM系列AirData万用表套件中的任何一个都可以与8400 FlowHood套件一起购买，也可以不购买。
