First, product introduction
Based on the relevant requirements of ASTM E1155M (floor flatness FF and floor level FL numerical standard test method), the function and usage method is similar to the Dipstick tester or D-meter in the United States.
♦The instrument consists of a test rack and a tablet computer, which is easy to assemble and maintain;
♦ The test software is all Chinese, in line with the habits of Chinese people, easy to use;
♦ It can directly read the flatness FF and FL values of the floor profile of the current test, or archive the Excel data table for all test data for later analysis;
♦ High-precision sensor with a single data resolution of 0.05mm and a test accuracy of 0.1mm (@25°C);
♦ All-aluminum body, light and easy to operate;
♦ High-capacity lithium battery guarantees long-lasting battery life;
♦ Provide supporting instructions and data analysis materials.
econd, related background
The F values are the American Concrete Institute (American Concrete Institute #117) and the Canadian Standard Association (Canadian Standard Association #A23.1) are standards for the specification and measurement of concrete floor leveling and height difference. This specification includes two F values: FF is flatness, FL is high difference, flatness is related to the elevation and depression of the floor; high difference is related to the inclination or height difference of the floor. That is to say, the flatness FF indicates the degree of fluctuation of the overall meaning of the floor, and the level FL indicates the degree of inclination of the overall meaning of the floor. The higher the F value, the better the flatness of the floor.
