Dwyer 477AV系列手持数字压力计可满足你对压力测量的需求,记录数据更快,更容易更准确。首先,你可以从九种常用单位里进行选择,省去在单位转换中计算错误和浪费时间。其次,可永久存储记录到40个读数-非常适用于采暖通风空调技术员在现场用皮托管测量空气流量。

当在光线暗的区域工作时,可打开背景光,20分钟后可自动断电,减少电池消耗。电子调零只需简单的按动一个键就可以完全清除差压。屏幕上的HOLD键可保持当前压力读数防备常常遇到的读数跳动情况。声光报警特别适合有环境噪声的场合。同时声音报警也可用于确定数值是否被存储,不必要在测量中一直盯住显示器观察。

477AV系列增加了USB选项,并结合了477的数据能力,用户能快速和方便的下载读数到任何一个USB装置。能在众多的文字和图表程序方便的进行数据处理,USB选项自带缆线和CD软件。
