small and medium size Sonde

Use sonde to detect the head position of glass filber cable in PVC pipe, but when there is RC bar on the top of pipe line, you need low frequency sonde to overcome the metal barrier

Some cases it use metalic pipe so we need low frequency sonde to overcome the metal barrier

We offer small and medium size sonde (520Hz ) for thios application

market offer high frequence sonde e.g. 8KHz,33KHz,112KHz wjat is the application? most of the application is for sewer pipe, most of the cases the pipe is big >8"(200mm)歐

In outdoor PVC piping casees people use high frequemcy sonde as high frequency is easier to do the job    

of course you need a receiver e.g. UT9020 to do this job
