1、Product introduction

The equipment is developed according to the industry standard, used for testing the wind pressure resistance of the external wall insulation system. The advanced control system is adopted in the control mode, including accurate pressure regulation of pneumatic control valve, automatic control of microcomputer, display of recording process control curve, printing of original records and testing results. The overall design has many advantages, such as wide adaptability, simple operation, stable performance, high control accuracy, accurate data collection and low noise synthesis.
