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.
