FALL CONE LIQUID LIMIT APPARATUS

SEIKEN,INC.

This device conforms to the soil liquid limit testing method with Fall cone established in 2000 (JGS 0142-2000). *JGS: The Japanese Geotechnical Society
The measuring way of ‚i‚h‚r A 1205 was pointed out many problems, for example, personal errors in test results because the way needed skills in the operation, Therefore, Fall cone testing method was standardized.
This testing method, that is, investigation of the liquid limit with taking relation between penetration value with free fallingof cone and water content of soil, are adoppted by many reserach centers& institutions becausethis simple operation makes no personal error in test results.

AUTO PENETRATION STOP TYPE@DH-22NA
Feature:
If you just press the penetration switch, it is Auto penetration stopped after 5 seconds. And there is no personal error in measuring.
Regarding the measuring of  penetration value, the specification can be changed to another with Non-attached Laser Displacement Transducer.
