Respirable Dust Samplers are needed to assess the work-related exposure to gases, dusts and vapors. They have been designed to work by the operator and can be located in the breathing zone. These are the instruments, made for measuring the properties of particulate matter in the ambient air. These can prevent the volatile fraction and allow for good portability. Respirable Dust Samplers we deal in provide noiseless operation. These are also featured with flow recorder and time indicators. They get auto shut off when the flow rate gets dropped. The samplers make no errors that occur due to pressure and temperature changes.
