Elast Logger-3i is an advanced digital pressuremeter capable of testing wide range ground from soft rock to hard rock in combination with Elastmeter Digital Sonde.
A series of operations can be performed from data recording of pressure and displacement to plotting of results. Mechanical information such as Young’s modulus can also be obtained quickly with Panasonic Tablet.
A thermal printer is available as an extra-cost option, and it enables users to print out obtained data at a site.
