Brief:Mask&Respirator Breathing Resistance Tester can be used to determine the inspiratory and expiratory resistance of masks under specified conditions.Another additional function of this machine is flow impact test of the breather valve. The flow rate for inhale resistance test is 30L/min and 95L/min. The flow rate for exhale resistance test is 160L/min. And the flow rate for the flow impact test is 300L/min.
Brief:The melt flow rate meter is suitable for the determination of the specified thermoplastic melt mass flow rate in the "GB/T3682-2018 Thermoplastic Melt Mass Flow Rate (MFR)and Melt Volume Flow Rate(MVR)" national standard. This standard is equivalent to The requirements of ISO 1133:2011 can also meet the ASTM D1238 test standard.
Brief:Mask Flame Retardant Tester is a special test instrument for flame retardant performance of medical masks, to test the flammability performance of medical mask after contacting with flame at a certain linear speed.
Brief:The resistance of medical masks to penetration of synthetic blood under different sample pressures can also be used to determine the blood penetration resistance of other coating materials.
Brief:Mask Bacterial Filtration Efficiency Tester is applied to test the filtration efficiency of mask, can be used in metering calibration department, scientific research institution, mask manufacturer and other related departments.
Brief:It is used to quickly, accurately and stably detect the filtration efficiency and airflow resistance of various masks, respirators, and flat materials, such as glass fiber, PTFE, PET, and PP melt-blown composite materials.
