Counterfeit Masks & Shields
There have been instances of N95 masks and shields that are imported, distributed without even minimal testing and found to be substandard. CMTL has been spot testing imported and domestically manufactured PPE for Local Health Integration Networks and operators of hospital groups. CMTL’s staff consisting of experienced engineers, scientists, machinists and technicians are able to respond quickly to changes in the types of testing required in these difficult times.
