Koden DM-602R 604R Ultrasonic Drilling Monitor

Easily to position and set up, the DM-602R & DM-604R provides quick and accurate recordings of excavations.  

  • Helps improve the quality of a drilled hole & reduces working time & cost
  • Provides on site records of the perpendicularity of drilled holes & the shape of cross sections in high accuracy
  • Provides numerical measurement data that can be easily imported into various Windows applications for work reports
  • Measurement range and depth data are indicated on the recording paper with wall face marks and numbers.

The DM-602R/604R supplies clear records of a drilled hole even in slurry, heavily contaminated with dirt and sand.

Clear and precise records are supplied due to the DM-602R/604R unique signal processing which discriminates wall echoes from the noise.  The drilling monitor 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, date, time, etc. can be printed on the recording paper.

Limit switches are provided to avoid possible wire breakage or entanglement of the wire and cable.  Recorded results can be outputted to an external PC via the RS232C output port.  A non-fuse circuit breaker is used for circuit protection, eliminating the need for cumbersome fuse replacement at the construction site.
