Mask detection  

Pony testing group was established in 2002. It is a national food re inspection organization and a postdoctoral research station listed in Beijing. The headquarter of pini group is located in Beijing. In 2006, puni testing group has become a high-level cooperative Laboratory of P & G, undertaking the R & D and quality appraisal of daily chemical products, disposable sanitary products and other products in P & G technical center.

The long-term cooperation with P & G has established the outstanding advantages of puni test in the field of mask testing. All laboratories in the group have the ability to detect masks, among which Shanghai and Beijing laboratories of Penney test group have all the testing capabilities!
