Universal type penetrometer is based on the geotechnical experiment: the penetration of soil and the dry density of soil, the relationship between the relationship between the penetration and water content of soil and the relationship
between soil water volume and compactness, through a lot of penetration and ring cutting parallel contrast test And establish
the regression equation, the rate of penetration resistance between the dry density and the related data sheet. By measuring the penetration resistance and looking up the table, the dry density can be quickly obtained, and then the compaction
coefficient can be quickly calculated. Two, main technical parameters
Principle
* High accuracy and high resolution.
* With 4 measurement unit for selection and conversion, kgf, gf, N, Lbf
* With peak value hold function.
* can memorize 99 groups of data.
* Digital display with no guessing or errors.
* With 10 minutes auto power off and manual power off.* Either alkaline battery Power supply or 5V DC power.
* Use USB cable or Bluetooth adapter for data output.
