Model 4400

Embedment Jointmeters (Vibrating Wire)

The Model 4400 Embedment Jointmeter is designed for use across construction joints, such as those between adjacent blocks in a concrete dam. It is normally embedded across the joint to monitor the expansion or contraction of the joint. The use of internal universal joints allows for a degree of shearing motion.
