Sequential high volume sampler for sampling up to 15 filters

High volume sampler for determining suspended particles in emission, with sample collection on filter and gravimetric determination in the laboratory. Sequential sampling up to 15 filters of 150 mm Ø Consisting of a suction assembly with centrifugal pump and electronic control circuitry of the system mounted in a polyester-fiberglass case suitable for working outdoors, with equipment support frame. Operation, measurement and regulation of the flow controlled by microprocessor. Automatic regulation of the programmed flow rate, with automatic compensation of load loss due to filter clogging or network fluctuations. Suction flow normalization for pressure and temperature correction. Communication interface with the user through a 240 x 128 p LCD screen and keyboard.
