CJSS30A digital track convergence meter/digital convergence meter

CJSS30A Digital Tunnel Convergence Instrument

CJSS30A digital tunnel convergence meter, digital convergence meter, convergence meter, 3A digital convergence meter (referred to as convergence meter) is a new generation of electronic digital display convergence meter. It is suitable for measuring the small distance changes between two points in any direction around the surrounding rock of tunnels, tunnels, chambers and other processes, achieving the purpose of evaluating the deformation development law of engineering surrounding rock and support, determining reasonable support parameters, and convergence measurement has become one of the underground engineering measurement projects. This convergence meter is a new product improved on the basis of the original Type 30, which won the Science and Technology Progress Award of the former Ministry of Coal. It has the characteristics of novel structure, easy operation, high measurement accuracy, small volume, light weight, and good sealing. It is an ideal tool for engineering measurement in construction and scientific research.
