Products: 
 "LHGD-J1 prestressed pipe (hole) said the quality of grouting detector" is specialized for the detection of pre-stressed cable bridge (hole) strand and concrete mortar paste knot state, grouting density, defects, voids, and the bit and the quality of cement mortar around the strand dedicated instrument. General test items are: the density of mortar, empty defects and the location of mortar plumpness, firmness anchor, mortar and paste strand knot state, anchor quality, defect size and location, and so on. 

 Applications: 
 This instrument is suitable, highway engineering, railway engineering, mining engineering, bridges, tunnels, mountain slope, urban construction. Can be combined on a strand and anchoring a variety of concrete pipes, tunnels and other conditions of implementation of project quality non-destructive testing. 

 How it works: 
 Instrument using acoustic transmission and reflection principle to implement non-destructive testing. Work at both ends by the host or transmit sound to the end of the sensor, acoustic emission time, arrival time, speed of sound, velocity, frequency and amount of energy reflected by intelligent analysis and processing software obtained after anchoring the overall quality of mortar.
