【Scope of application】
It is used to quickly and accurately detect the protective effect of various flat masks and 3D masks on particulate matter.
【Compliance with standards】
GB/T 32610-2016 Technical specification for daily protective masks 6.14 Protective effect Appendix B Test method for particulate matter protection effect,
GB/T 38880-2020 Technical specifications for children's masks and other standards.
【InstrumentFeatures】
1. The photometer sensor is used to detect the concentration of upstream and downstream particles to ensure the accuracy, stability, speed and effectiveness of sampling.
2. The system test flow rate is mainly provided by the outside to provide dry and clean compressed air. There is a voltage stabilization device installed inside to ensure the stability of the detection flow, and the automatic control system is simple, fast and stable.
3. Adopt Collision multi-nozzle design, which can test salt and oily particulate matter on the same instrument to ensure fast and stable adjustment of mist concentration.
4. It can be equipped with GB∕T 38880-2020 children's mask test sports silicone head mold.
5. Configure artificial respiration simulator, which can set the expiratory volume and respiratory rate arbitrarily.
