Wall brick shrinkage and expansion meter is a testing instrument, suitable for wall brick production plants, scientific research units, colleges, construction departments and other units to detect the shrinkage and Amount of expansion deformation. Be sure to read the instructions carefully before use. It is operated by experimental personnel to avoid injury caused by improper operation. For more information, please contact our customer service staff.

砌墻磚收縮膨脹儀是由：底座、試樣架、測量表架、上測頭、緊固螺釘、下測頭、百分表、標準桿、試體固定螺釘、底座調整螺絲等組成。該產品是依據(jù)GB/T2542-2012《砌墻磚試驗方法》標準設計制作，上下測頭采用90°錐形凹座。具有使用方便、測量精度高、速度快、讀數(shù)清楚等特點。

The masonry brick contraction and expansion meter is composed of a base, a sample holder, a measuring meter holder, an upper probe, a fastening screw, a lower probe, a dial indicator, a standard bar, a test body fixing screw, and a base adjusting screw. This product is designed and manufactured in accordance with GB / T2542-2012 "Test Methods for Masonry Bricks". The upper and lower probes use 90 ° conical recesses. With easy to use, high measurement accuracy, fast speed, clear readings and so on.

砌墻磚收縮膨脹儀主要技術參數(shù)：

★百分表量程：0～10mm；小刻度值: 0.01mm；

★標準桿長度：（256±0.02）mm；標準桿測頭球面半徑：SR=2.25mm；

★測量范圍：251mm～261mm

★外形尺寸：320X300X550mm

★重量：約12kg

Main technical parameters of wall brick shrinkage and expansion meter:

★ Dial indicator range: 0 ~ 10mm; small scale value: 0.01mm;

★ Par length: (256 ± 0.02) mm; spherical radius of the par probe: SR = 2.25mm;

★ Measuring range: 251mm ～ 261mm

★ Dimensions: 320X300X550mm

★ Weight: about 12kg

砌墻磚收縮膨脹儀注意事項：

★使用時，忌用手直接與標準棒接觸，應持外外套部分，以防止標準棒受人體手溫的影響。

★儀器用完畢后，應將測量框架的測量頭和百分表探拭凈，并涂以鐘表油；測試過程中，應使百分表的測頭緩慢而平穩(wěn)地與試件接觸，不允許沖擊和碰撞，嚴禁將百分表測桿頂過A大量程范圍，以免影響表的靈敏度和使用壽命。

Note for wall brick shrinkage and expansion meter:

★ When in use, do not touch the standard rod directly with your hand, and you should hold the outer jacket to prevent the standard rod from being affected by human hａnd temperature.

★ After the instrument is used, the measuring head and dial indicator of the measuring frame should be cleaned and coated with clock oil; during the test, the dial indicator should be brought into contact with the test piece slowly and smoothly. For impact and collision, it is strictly forbidden to push the dial gauge rod over a large range of A to avoid affecting the sensitivity and service life of the meter.

砌墻磚收縮膨脹儀試驗方法：

★先將標準棒置于工作臺上，擰動調整螺絲使之近似垂直。

★將測量框架置于標準棒的頂頭，調整螺桿和螺母，使百分表對準零位（或記下百分表之刻度）。

★將制作養(yǎng)護好的試件兩端擦拭凈，然后放置在工作臺上，然后把測量框架套在試件上，并左右移動表框，使試件與測量框架的測量頭準確地接觸，此時即可開始讀數(shù)，并記錄下表盤上的刻度值。

★如果實驗不是連續(xù)進行或實驗歷時較

Test method for contraction and expansion of wall bricks:

★ Put the standard rod on the workbench first, and turn the adjustment screw to make it almost vertical.

★ Place the measuring frame on the top of the standard rod, adjust the screw and nut to make the dial indicator align with the zero position (or write down the dial indicator scale).

★ Wipe the two ends of the prepared and cured test piece, then place it on the workbench, then put the measuring frame on the test piece, and move the table frame left and right, so that the test piece and the measuring head of the measuring frame accurately contact. You can start reading and record the scale value on the dial.

★ If the experiment is not continuous or the experiment lasts longer
