Product Description

Borehole Caliper Survey Logging System 1m 2m 3m Diameter Borehole Logging Tools Concreted Piles Diameter Testing Instrument Borehole Diameter Survey Tools

                                     

 

It has characteristics:
The measuring probes underground are totally digitized.
The measuring probes underground are stainless steel materials.
Equipped with a automatic cabling winch.
The caliper/inclinometer measuring probe and sediment/inclinometer measuring probe become one. 



Convenient to operate.   
The hole diameter measuring bias reduces to 5mm.
The control case adopts industrial computer, it is easy to operate and has strong anti-interference ability, it also can judge the model of the probe underground automatically.
The operation software is suitable for WIN XP/WIN VISTA/WIN 7.
It is the upgrading product of JJC-1D which is accepted and popular among the customers. It improves the work efficiency and quality.
