Elast Logger-3i & Elastmeter Digital Sonde
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.
Features
- By converting the measured value into a digital signal inside the digital Sonde and transmitting it to Elast Logger-3i, the signal transmission stability is improved.
- User-friendly operating system by Panasonic Tablet controller.
- High brightness color LCD allows clear visibility even under direct sunshine.
- From the measurement of pressure to the displacement, easy and understandable displacement curves are available.
- By connecting "Digital Converting box for Elastmeter HQ Sonde", Elast Logger-3i is available to connect Elastmeter HQ Sonde (Model-4180) and Control cable for Elastmeter Digital Sonde.
