DM-602/604 Ultrasonic Drilling Monitor for Construction

Koden's Drilling Monitors shape up to more intelligent utility device intended for more complex civil and foundation work.
The new DM-602/604 with additional functions offer precise measurement, display and recording of perpendicularity of drilled holes and the shapes of cross-sections.
Easier and simpler to operate. You can manipulate the DM-602/604 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.

Drilling Monitor in South East Asia
Koden Drilling Monitor DM-602/604 can measure and confirm for underground foundation work, the state of wall surface, pile diameter, deflection and incline, namely the "vertical accuracy" of the drilled hole or excavated wall.
International foundation projects both home and many Asian countries nominate the DM-602/604 as the official tool to measure the various key indexes.
The projects include:
Metro Project in India
Subway Project in Singapore
Skyscrapers in Hong Kong
LNG Project in South Korea
Railway Project in Taiwan
Metro Project in Thailand
Inchon LNG Project in South Korea
