While sold as a dual-mass model, the S-222 can quickly be converted to a single mass unit by removing the hexagonal set screw and removing the outer sleeve from the dual mass hammer. This procedure can be accomplished during a test, since the outer sleeve is designed to slide over the DCP handle. The cone penetration caused by one blow of the 8 kg hammer is essentially twice that caused by one blow of the 4.6 kg hammer. As a result, the 4.6 kg hammer is more suitable for use and yields better test results in weaker soils having CBR of 10% or less. It can also be used for evaluating soils in foundations for residential structures which require bearing value of 2000 PSF (approximate CBR of 6%). The 8 kg hammer is preferable for high-strength soils, which it penetrates more quickly than the 4.6 kg hammer. However, the 4.6 kg hammer can be used on soils up to CBR 80%.
The S-222 includes:
- dual-mass slide hammer assembly
- 1-meter drive rod with hardened tip
- disposable cone tip adapter
- 25 disposable tips
- vertical scale
- go/ no-go gauge
- all necessary wrenches
- user manual with spreadsheet software template
- heavy-duty, crush-proof Pelican carrying case
