The Enviko SK-AR vibrating wire anchor rod stress meter monitors stress changes in anchor rods or reinforcing bars in concrete and other structures. Its ends are welded into the anchor rod being monitored, or machined into threaded connections to the customer's dimensions. Several meters can be installed along one rod in a fully grouted borehole. A built-in temperature sensor records the temperature at the installation point.
