Overview
LANDTEK FM204-DJ Fill Compactness/Platts Penetration Instrument is an instrument based on the relationship between penetration and dry density, water content and compactness in geotechnical tests. Through a large number of parallel comparison tests of penetration and ring knife method, the regression equation is established, and the data table related to penetration resistance and dry density is calculated.
Features
1. No radioactive nuclear contamination
Step 2: Cheap prices
3. Compact size, easy to carry on site
4. The test is fast, only 15-20 minutes for a set of tests
5. Effectively increase productivity
Principle
The Platts penetration meter is based on the correlation between soil penetration and dry density, water content and compactness. The regression equation is established through a large number of parallel comparison experiments between penetration and ring knife method, and the correlation data table between penetration resistance and dry density is calibrated. During measurement, the dry density is quickly obtained by looking up the penetration resistance table, and then the compaction coefficient is calculated.
Applications
Civil and industrial buildings, highways, railways, roads and bridges, municipal drainage, oil pipelines, water conservancy, dams, dikes, irrigation channels, reservoir construction, airport runway projects
Steps
1. Prepare the instrument and install 2 AA batteries (optional 5V DC)
2. Select the test point and insert the probe into the tested soil
3. measurement of penetration resistance
4. Look up the table to get dry density
5. Calculate the compaction factor
6. After the test is completed, you can manually shut down or wait 10 minutes for automatic shutdown.
