1. A new kind of miniature cone penetrometer was developed in order to acquire automatically the cone penetration resistance and depth in MCPT.

2. The Penetrometer PNR 12 is suitable for measurements according various "Bitumen" methods.

3. Cone index penetrometer is a special apparatus widely used for assessing soil compaction in agriculture.

4. A series of tests with the portable dynamic penetrometer of type PANDA have been carried out, to inspect the grinding quality of the secondary ash dam.

5. The static continual penetrometer increases the efficiency and quality of static penetration.

6. Paint coatings for indoor use. Measurement of consistency by penetrometer.

7. The welding quality of sheathed thermocouples was investigated by X ray testing. The design of penetrometer, the testing method, and the testing results were introduced.

8. Paint coatings for interior use. Evaluation of durability by successive measurements of consistency with a penetrometer.

9. After a brief introduction of the principle of the portable dynamic penetrometer with variable energy, its application to loess was presented.

10. Tentatively, this study introduced simple and economical Dynamic Cone Penetrometer (DCP) and Impact Soil Tester (IST) for facilitating the investigation of subgrade and upgrading its quality.

11. Evaluation of durability by successive measurements of consistency with a penetrometer .
