Four channel fully automatic pneumatic preloader

The four channel fully automatic pneumatic preloading instrument is a new type of indoor geotechnical testing instrument specifically designed to provide pre compaction work for soil samples in direct shear tests. It utilizes cutting-edge technological achievements that integrate mechanical and electronic technology, sensor detection technology, automatic control technology, and computer intelligence technology, and can automatically complete the loading and unloading of pressure during the preloading test process. Its pressure source adopts pneumatic method, which is stable and reliable, and can replace early products such as lever preloaders.
