I. Application:
The DJGW-2A apparatus is mainly used for the test of concretetruc-ture's quality, confirming the position of the steel bar, protecting the thickness of floor and the diameter of the steel bar. It also can test the position of the metal involved in the nonmetal, such as the cable in the wall and the metal involved in pipelines and woodiness.
II. Main function
1\Testing the position of the steel bar
2\Testing the thickness of the protecting floor
3\Testing the diameter of the steel bar and the thickness of the protecting floor
4\Section plane test
5\Internet test
6\Data's storage and examination
7\Data's transfers
III. Main index of the technology
1\The range of the steel bar's diameter: Φ 6MMA~Φ 40mm
4\the range of the diameter's test: Φ 6mm~Φ 40mm
6\The capacity of data storage
(1)The single DOT test can store 300 parts, every part can store 99 pieces of steel bar.
(2)Section plane test can store 150 parts, every part can store 99 pieces of steel bar.
(3)Internet test can store 100 parts, every part can store 150 pieces of steel bar.
7\The requirement of the work conditions
