Abstract
The utility model relates to a concrete spring back thickness tester, which is composed of a thickness tester mainframe and a receiving probe, wherein the mainframe comprises a mainframe casing, a control circuit board, control buttons, a built-in power source and an external jack; the receiving probe is connected with the external jack through a connection cable plug, and composed of a probe casing, a piezoelectric ceramic block and a connection cable. The piezoelectric ceramic block is encapsulated in the front of the probe casing, and the rear end face of the piezoelectric ceramic block is connected with the connection cable. When the thickness of a measured object is measured, the thickness of concrete can be fast measured without aligning the probe, so that the problem that people are unable to reach the other surface of the measured object and can not carry out measurement in certain occasions is solved. The utility model has the advantages of simple structure, convenient maintenance and operation, small size, convenient carryover and high measuring precision.
Description
Technical field
The utility model relates to a kind of survey instrument, refers in particular to, a kind of concrete springback thicknessmeter that utilizes the impact echo principle and design.
Background technology
