Balloon Method Soil Density Testing Apparatus

The balloon volume meter is based on Boyle's law of physics; During the test, a certain pressure is used to push the piston to transfer the medium (air) in the cylinder to the air bag placed in the test pit, so that the air bag expands close to the inner wall of the test pit; Record the data displayed by the measuring device and calculate the volume of the test pit.

Technical parameters:
Cylinder volume: 5200cm3
Piston stroke: 280mm
Air bag pressure: 8KPa
Digital display depth ruler resolution :0.01mm
Volume constant piston area ×0.1cm3/mm
Detection error: ≤ 1%
Test pit size :Φ150mm×200mm
Handle operating force :≤200N
The machine weight :5.2kg
Dimension :Φ255mm×627mm
Instrument composition: air bag type volume measuring instrument is mainly composed of air bag, cylinder, piston, pressure mark, digital depth ruler, pit ring, pedal.
