1. Detection on compactness of bridge channel grouting;
2. Detection on defect location of bridge channel grouting.
Product features:
1.Synchronization realization of detection on compactness of bridge channel grouting and its defect location.
2. Test method of compactness of bridge channel grouting: transfer function method,
Test method of channel defects: equivalent wave velocity method;
3.Number of channels: 2 channels. The function of them is interchangeable, both can be used as transmission channel as well as receiving channel;
4. Operating mode: supporting dual control of touch screen and photoelectric knob;
5. Supporting Beidou positioning;
6. It can be docked with BEQRMES (Building engineering quality remote monitoring and evaluation system), and thus can realize remote control and quality evaluation.
