Sandy Minimum Density/Maximum Density test Apparatus

SEIKEN,INC.

These are measuring devices in accordance with "Testing Method of Sandy Maximum Density/Minimum Density" (JGS 0161) established in 2000. And the description about mechanization of Minimum/Maximum density test equipment in "Soil Testing Method and Explanation" (The Japanese Society of Soil Mechanics and Foundation Engineering) is based on our products.
There are many problems in both Minimum and Maximum Density tests, for example, individual errors are caused easily in both tests, the different result is gotten every testing day even if the same staff. And the results depend on the staff condition, storing up of fatigue, etc.
However, we actualized automatic test apparatuses and lots of tests have been done with them in real. And we kept revising them in accordance with our customer's opinions and requests. They can work accurately, for example, it has the actual proof that it can measure the maximum density within 1.646 +/- 0.001g/cm3 and the minimum Density within 1.335 +/- 0.001g/cm3 with Toyoura Sand. Therefore, you can use it without anxiety.@

Automatic type Minimum Density Test Apparatus@DAA-112
Feature

This apparatus is stopped automatically when the pouring of specimen by motor is finished. Removing the extra-banking part is done with the equiiped cutter automatically. There is no individual error in measuring because of the full automatic system.

Main Specification
Specimen Container Inner Size dia.60~40mmH
Collar Inner Size  dia.60~20mm
Motor 100V,6W
Automatic type Maximum Density Test Apparatus@DAA-114
Feature

This apparatus can set a fixed value of specimen in the container with lever type shutter after pouring by the hopper. Knocking is repeated from every direction by  motor,  stopped 100 times at 1 layer automatically with the  preset counter.  After 10th layer's knocking, the extra-banking is cleared by the straight edge after removing the collar. There is no ndividual error in measuring because of the full automatic system.
