VWJ type vibrating wire seam gaugeDetailed product description：

The VWJ vibrating wire type joint meter is suitable for long-term installation inside and on the surface of concrete structures or other material structures, measuring the opening and closing degree (deformation) of expansion joints or peripheral joints of structures, and can synchronously measure the temperature of buried points. Installing supporting accessories can form instruments for measuring deformation such as bedrock displacement meters and surface crack meters.
