[0002] The jump tables (fluidity testers) currently on the market are all made in accordance with the relevant provisions of Appendix A "A.2 Technical Requirements" of "Method for Determination of Fluidity of Cement Mortar" GB / T2419-2005. They are driven by synchronous motors and output fixed frequencies. It is impossible to achieve free switching of multiple frequencies on one device. Common models are: NLD-3, NLD-5 and three jump tables for high-speed railway cement emulsified asphalt mortar dry material detection.
