Sequential low volume sampler for sampling up to 30 filters

“Low volume sampler for the gravimetric determination of the mass concentration of PM10 or PM2.5 of the suspended particulate matter, with sample collection on filter and determination in the laboratory. With a capacity of up to 30 filters. IoT connectivity. Consists of a suction assembly with paddle vacuum pump, suction head, filtration system and electronic system control mounted in a polyester-fiberglass case suitable for outdoors and aluminium frame/support that allows fixing to the ground. Filter holder for filters of 47 mm Ø. Filters easily changed by means of container-filter holder. Forced ventilation and cooling system of the storage chamber of sampled filters below 20ºC. Particle head for PM10 or PM2.5 built according to the specifications included in UNE-EN12341:2015, with insulation of the connection tube and air sleeve. Constant ans automatic control the programmed flow rate, with automatic compensation of load loss due to filter clogging or network fluctuations. Flow measurement using orifice plate (according to EN 5167).”
