Koden’s Drilling Monitor(DM) provides on site records of the perpendicularity of drilled holes or diaphragm wall, and the shape of cross sections in high accuracy.
The DM shapes up to more intelligent utility device intended for more complex civil and foundation work. The DM-602RR/604RR/604RR-125 with additional functions offers precise measurement, display and recording of perpendicularity of drilled holes and the shapes of cross-sections.
Features
- Easier and simpler to operate. You can manipulate the DM-602RR/604RR just like a home appliance.
- Gain control switch, auto and manual, is provided.
- Clear and precise records make your data reading and analysis easier.
- Measurement range and depth data are indicated on the recording paper with wall face marks and numbers.
- Furthermore, the recorded data can be output to an external PC via a built-in RS 232C output port.
