The PANDA® Instrumented DCP measures and displays a material’s in-situ resistance to penetration through the depth profile of the material. The setup is extremely mobile and able to investigate areas with limited access or height restrictions. For example, it can be used in basements, on very steep slopes, in back yards and tunnels.
- The typical operating range of the PANDA® is 4-6 meters depth in soils with a cone resistance of 20-30 MPa.
- 2 cm² fixed cones and 4 cm² lost cones
- Variable energy (1.7 kg manual Hammer, 10 kg automatic hammer)
- Used for compaction control and site investigation
- Portable method for evaluating soil strength
- Immediate repeatable results so that on-site decisions can be made straight away
- Good for testing in challenging conditions (e.g. remote, soft, marshy, over-water or confined spaces).
