help improve the quality of a drilled hole and reduces working time and cost
- provides on site records of the perpendicularity of drilled holes and the shape of cross sections in high accuracy
- provides numerical measurement data that can be easily imported into various windows applications
Features :
The DM-604RR supplies clear records of a drilled hole even in slurry , heavily contaminated with dirt and sand
- it has the facility to cancel the oscillation line echo that often prevents very close echo recordings
- the sensor device is automatically controlled to stop at the casing and at the bottom of the hole . an emergency return function is also included .
- depth range mark ,depth mark , drilled hole mark , data ,time .can be printed on the recording paper
