Envilogger G1

A fully digital logger system allowing maximum user control. Bluetooth powered data transfer.

The G1 system is a digital logger system for recording drill data. A CAN bus for up to 64 CAN open sensors is used for data communication. Presentation can be done on any type of PC.

The system can record the following:

Drill data
Current drill depth
Rate of penetration = Drill speed
Hammer Pressure
Rotation Pressure
Flush Pressure
Rotations per minute (RPM)
Rotation count (Number of half turns per 10,15 or 20 cm)
Feed force calculated from thrust and holdback pressure
Flow volume
Time for 10, 15 or 20 cm increase in drill depth
Blow count för SPT, DPSHA, Hejarsondering etc
Blows per 10,15 or 20 cm
Probe data

Protective PC box


If you want to protect your PC you can add the PC protection box. This is made of 2.5 mm stainless steel and has a window so you can see the PC also with the lid closed. We have several variants in store but you can also order a tailor made protection box. All types of protection boxes work better with external keyboard added, and even better if you add the Envi Keypad too.
