Embedment Jointmeters (VW)

Embedment Jointmeters (VW)
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. Specifications Standard Ranges¹ 12.5,…
