Product Details
Overview
The Enviko SK-DMP series multi-point extensometers are installed
directly in boreholes to monitor deformation or settlement across
multiple slip surfaces and zones. Apart from the rod protection
tubes and anchors, the instruments are made entirely of stainless
steel. They offer high accuracy, a simple and shock-resistant
construction, easy installation and stable long-term readings, and
support long-distance transmission and automated monitoring. A
built-in temperature sensor records the temperature at the
installation point, and a smart ID chip can be fitted on request.
