Measurement methods:
●Automatic measurement
The sensor runs parallel to the steel bar and sweeps directly above the steel bar at a constant speed. The instrument emits a beep to prompt the sensor to cross a steel bar. At this time, the protective layer display value is automatically updated to the protective layer thickness value at that place.
●Manual measurement
If the spacing between steel bars is less than that described in the above table, manual measurement methods are required to determine the thickness of the protective layer.
The sensor is parallel to the direction of the steel bar, sweeping directly above the steel bar at a constant speed, and the thickness of the protective layer is determined according to the current display value of the distance and the change of the signal value.
●Minimum protective layer thickness measurement
This function is mainly used in the following occasions:
1. Quickly check whether the thickness of the concrete protective layer meets the minimum design value, and alarm for abnormal points;
2. After the template is removed, check whether the steel bars are pulled out.
Product Description:
● The first automatic interpretation function under the dense distribution of steel bars, which is especially suitable for the requirements for the detection of the position of the steel bars in the beam components and the thickness of the concrete protective layer;
● A single comprehensive probe detects the thickness of the concrete cover and the diameter of the steel bar at the same time, which is especially suitable for the detection work under the condition of incomplete original construction data.
● The thickness of the protective layer can be measured up to 180mm, which is especially suitable for the requirements for the detection of the position of the steel bars in the plate members and the thickness of the concrete protective layer. The main function:
● Scan the position and direction of the steel bars inside the concrete;
● Accurately measure the thickness of the concrete protective layer of the steel with a known diameter;
● Measure the diameter of steel bars of unknown diameter and the thickness of the concrete protective layer. Performance characteristics:
● Single integrated probe, no need to replace during detection, fast speed; detection depth up to 180mm, measurement accuracy up to ±1mm;
● Large-screen reflective LCD display, suitable for field operations;
● All Chinese display, friendly man-machine interface, easy to learn and use;
● Store inspection data of 1000 components, each component can store 256 measuring points;
● The thickness of the protective layer of the component is displayed and statistically analyzed;

● The stored data can be transferred to the computer for processing.
