DM-Ⅲ打磨性测定仪是用于评价底漆、腻子打磨性优劣的装置。本装置对待测定的底漆、腻子试样进行来回打磨，打磨次数可由计数器直接读取，根据负荷重量、打磨次数与磨损程度，可评定该底漆、腻子耐打磨的性能。本仪器采用磁性吸盘，试样装卸方便。 主要技术参数1.磨擦速度：        0-135次/分（单程）2.置数范围：        0-9999（双程计数）注：显示次´2为打磨次数3.荷重：            打磨头：570±15g 附加砝码：50g 100g 200g4.电源：            220V  50Hz5.功率：            60W6.外形尺寸：        300mm´280mm´380 mm（长´宽´高）7.整机重量：        25KgDM-ⅢSanding Property TesterSanding Property Tester is applicable to evaluate sanding performance of primer coat and putty. This instrument carries out back and forth sanding for preparing measured primer coat and putty. Sanding times can be directly read by counter.. According to load weight, sanding times and abrasive degree, it can be used to evaluate sanding resistance performance of primer and putty. This instrument adopts magnetic suction pad, for easily handling specimen.Main Technical Parameters1. Abrasive speed: 0-135 times/min (single pass)2. Range of setting value: 0-9999 (counting by double pass) Note: displaying number times two is sanding number.3. Load weight: grinding tool 570±15g  Additional weight: 50g 100g 200g4. Electrical source: 220V 50Hz5. Power: 60W6. Overall dimension: 300mm´280mm´380mm（length by width by height）7. Weight: 25kg 上海现代环境工程技术有限公司 公司地址：上海市昭化路508号新衡公寓405室  电话：64397454  传真：62268724  邮编：200050厂   址：上海市青浦区徐泾镇徐旺路18号     电话：59884086  传真：59884051  邮编：201702
