Product Mode： Fixed mode of products： Test Speed： Number of tests： Equipment size： Description: This testing system is specifically designed for testing the performance of radiators. GB/T 1236-2017 Standardized Duct Performance Test for Industrial Ventilators AMCA210-07 The entire control and testing system adopts automatic control mode to meet the needs of performance testing for various radiators and fans. The automatic control and measurement method of this testing system adopts a computer centralized distributed measurement and control system design. The lower level control machine composed of a data system collects and displays data, while the upper level main control computer analyzes and processes the data collected by the lower level control machine, and sends setting value instructions and data acquisition instructions to the lower level control machine to complete the work of the entire system. The measurement principle of this testing system is the obstruction type flow measurement principle, using a standard long diameter low-speed nozzle as the obstruction, and measuring the air flow through the nozzle by measuring the static pressure difference at both ends of the standard nozzle. The measurement range of this testing system is 2.5-250 CFM. Static pressure range: 0-200mm Aq
