We use the universal testing machine in the process, there may be a sudden shutdown of the equipment, when encountering this situation, the user should learn to analyze the causes of the failure, and according to the specific reasons to seek solutions. Today I will briefly analyze the causes of the machine's downtime and the corresponding solutions, including the introduction of maintenance and repair methods.

The electric density gauge strictly enforces national standards and is an instrument for measuring the density and compaction of hot mix asphalt pavement. Electric density gauge adopts electromagnetic induction technology instead of nuclear source radiation method, low cost, high safety, users do not have to worry about the cumbersome EIA application, time-consuming training, and harsh transportation control. With simple calibration, high accuracy, repeatability, and touch screen operation, the electric density gauge allows users to complete relevant operational training and master the techniques of on-site quality inspection in a short period. The electric density gauge can quickly measure the road separation, low density, uneven areas. Next is an introduction to the use and precautions of the Densitometer.
