According Standard:
Code for acceptance of constructional quality of concrete structures GB 50204-2002
Work Principle:
Electromagnetic pulse method: Ultra-force anti-interference.
Specification:
The DJGW-2A apparatus is mainly used for testing concrete structure's quality; locating the steel bar's position and Measuring the rebar's protecting thickness and diameter. It also can locate metal material's position involved in the nonmetal material, such as the cable, the plumbing pipe in the wall and the metal involved in pipelines and woodiness.
Display Magnetic induction with Digital and Imitation mode (Our Patent), and adopt Multi-parameter sensor to avoid interference of adjacent bar when bar is intensive.
Coating thickness and Rebar signal video display at real time; lock the min data and store, easily for operation.
High and Low-two range work mode to confirm the accuracy and depth.
Adopt no-side Grid and Section Scanning; Auto test and record Distance among rebar; and display rebar's location in concrete at real time.
Can test High Accuracy and Intensive rebar, which break traditional rule:
Rebar Distance compare with Coating thickness ≥2:1
With high Black light, even can work at underground and cave.
Bigger Data processing and Retest workshop's data function to guide users.
Special data analysis software, to PC to generate test report automatically.
Main Function:
Locating the steel bar's position and Measuring the rebar's protecting thickness and diameter. And also other function:
1. With Grid test method; two directions continuously scanning to display Grid figure.
2. With Section test Method: a direction continuously scanning to display Section figure.
