Soil ballloon In Situ Soil Density apparatus
It calculates the dry density of the soil after compaction by precisely measuring the volume of the excavated hole. Thanks to its elastic membrane, it conforms perfectly to the unevenness of the ground, providing a much more accurate volume measurement than other manual methods. A complete system that is easy to transport and maintain, designed to last on your road, utilities, and earthwork sites. NF P94-053 standard.
Components: Graduated cylinder, set of 6 high-strength rubber membranes, base plate, anchoring pins, and manual pump. Measurement range: Optimized reading accuracy across the entire column. Accuracy: Fine graduations for precise volume readings.
