Product introduction:

Gypsum moisture deflection tester is a testing instrument designed and manufactured in accordance with the standard requirements of gypsum standard JC / T799-2007 for gypsum. A number of new products launched by Rongjida Instruments have been well received, and we have always adhered to the belief of innovation and hard work. Continue to work hard to provide customers with better products and services.

技术参数：

1、装饰石膏板受潮挠度测定仪是根据JC/T799-2007标准设制的。

2、使用环境：水泥养护实验室：温度在（32+2），相对湿度（90+3）

3、装饰石膏板受潮挠度测定仪检测样品：500X250X9或600X300X11(mm)的3组。

4、按试验要求需要配3套夹具，每套夹具都配精度为0.01mm的专用尺和水平尺各一把。

5、将试块烘干，然后将每块试件正面向下，分别悬放在受潮扰度测定仪试验箱中三个试验架的支座上，支座**距为试件长度减去20mm，在文档为32度空气相对湿度90度条件下，讲试件放置48h，来源专用测量头。

6,外形尺寸:600*500mm

7,  重量：40kg

8,受潮挠度的测定仪规定的3块试件按5．3条烘干至恒重，然后将每块试件正面向下，分别悬放在受潮挠度测定仪试验箱中三个试验架的支座上，支座**距为试件长度减去 20mm。在温度为32±2℃，空气相对湿度为90％±3％条件下，将试件放置48h。然后将试件连同试验架从试验箱中取出，利用专用的测量头，分别测定每个试验架上试件中部的下垂挠度。计算3个块试件受潮挠度的平均值，并记录其中的大值，**至lmm。

Second, the technical parameters

1. Moisture deflection measuring instrument for decorative gypsum board is designed according to JC / T799-2007 standard.

2. Operating environment: Cement conservation laboratory: temperature at (32 + 2), relative humidity (90 + 3)

3, decorative plaster board moisture deflection tester detection samples: 500X250X9 or 600X300X11 (mm) 3 groups.

4. According to the test requirements, three sets of fixtures are required, and each set is equipped with a dedicated ruler and a level ruler with an accuracy of 0.01mm.

5. Dry the test block, then suspend each test piece face down, and suspend it on the supports of the three test stands in the test box of the moisture disturbance tester. 20mm, with the document at 32 ° C and relative humidity of 90 ° C, the test piece is placed for 48h, and the source is a special measuring head.

6, overall size: 600 * 500mm

7, Weight: 40kg

8. The 3 test pieces specified by the moisture deflection tester are dried to a constant weight according to 5.3, and then each test piece is face down and suspended on the three test stands in the test box of the moisture deflection tester. On the support, the distance from the support ** is the length of the test piece minus 20mm. At a temperature of 32 ± 2 ° C and a relative humidity of 90% ± 3%, the test piece was left for 48 hours. Then remove the test piece from the test box together with the test rack, and use a special measuring head to measure the sagging deflection of the middle of the test piece on each test rack. Calculate the average moisture deflection of the three test pieces, and record the largest value, ** to lmm.
