鋼筋保護層厚度檢測
​
BS 1881 : Part 204 : 1988
在評估結構的耐用性，知道鋼筋上的混凝土保護層厚度是很重要，這檢測能探測保護層的厚度，鋼筋的位置和直徑。

Covermeter Survey
​
BS 1881 : Part 204 : 1988
In assessing the durability of the structure, it is important to know the thickness of the concrete protective layer on the steel bars. This test can detect the thickness of the protective layer, the position and diameter of the steel bars.

原理
​Principle

探測儀磁化混凝土內的鋼筋，並量度其誘導電流▲
​The detector magnetizes the steel bars in the concrete and measures the eddy current.▲

應用範圍:
​

• 鋼筋和金屬管道的定位
• 混凝土保護層的厚度量度
• 判斷鋼筋的直徑

Application Scope:
​

• Positioning of steel bars and metal pipes
• Thickness measurement of concrete protective layer
• Determine the diameter of the steel bar​

鋼筋測量

鋼筋測量是用來記錄已暴露鋼筋的種類、直徑、生銹程度、生銹種類和橫切面的損失，所有資料都會用圖表作記錄。

Rebar Measurement

Rebar measurement is used to record the type, diameter, degree of rust, type of rust, and loss of cross-section of the exposed rebar. All data will be recorded with graphs.
