Several meters of the set, such as phase detector, damping tester, distortion meter and magnetic-fluxdetector, are briefly introduced in the paper.
文中简要地介绍了这种系列测试设备中的相位测试仪、阻尼测试仪、失真度测试仪及磁通量测试仪。

The acoustic energy fluxdetector based on vector hydrophone using counteractive technique of spacial acoustic energy flux, can obtain spatiotemporal gain proportion with time-bandwidth product.
The precision of count and speed test of inductive loop vehicle detector relates the veracity of traffic flux statistical result, which is verifiable key item.
