Testing and structural health monitoring can provide all testing services related to stress and strain parameter measurement, such as normal temperature outdoor environment, underwater environment, high temperature 800 ℃ environment, ultra-low temperature (-196 ℃) environment, strong magnetic and electric field (5000 Gauss and above) environment, large plastic deformation, civil engineering, residual stress, crack propagation and other strain testing services, and structural health monitoring. In addition to stress-strain testing, it can also measure multiple physical parameters such as displacement, temperature, vibration, force, bending moment, torque, etc., as well as structural health monitoring and evaluation based on this evaluation.
