Description
Range hood air volume and energy efficiency testing equipment
1、 Product Introduction
This equipment is an air volume testing system developed and manufactured according to the IEC61591 standard using advanced Japanese technology. Colleagues have installed a range hood air performance testing device in accordance with Appendix C of the GB/T17713-2011 “Range Hood” standard, which is an external exhaust range hood air performance testing device. It can measure the corresponding curves of static pressure and air volume, air volume and speed, current, power, efficiency, etc. It is also possible to test the sample in both inhalation and discharge states. It has the characteristics of convenience, speed, stability, reliability, and good reproducibility, and is suitable for testing and use in scientific research and production processes of related products.
