Low volume sampler for sampling a filter

Medium volume sampler for determining the mass concentration of PM10 or PM2.5 of the suspended particulate matter, with sample collection on filter and determination in the laboratory. Consists of a suction set with paddle vacuum pump, suction head, filtration system and electronic system control. Mounted on a weatherproof polyester-fiberglass case and aluminum support frame, which allows fixing to the ground. Operation, measurement and regulation of the flow controlled by microprocessor and mass flow measurement. Automatic regulation and constant maintenance of the programmed flow rate, with automatic compensation of load loss due to filter clogging or network fluctuations. Continuous measurement of air temperature, sample temperature and atmospheric pressure. Communication interface with the user through a 240 x 128 p LCD screen and keyboard. Internal memory for data storage, accessible by RS232/USB. Filter holder for filters of 47 mm Ø. Filter easily changed by means of filter holder. Electromechanical closure system for filter holder valves with filter position detector. Forced ventilation and heating system. Particle head for PM10 or PM2.5 built according to the specifications of EN 12341:2014, with thermal insulation of the connection tube and optional air sleeve.
