LOW VOLUME AIR SAMPLER MCV CMV-1D/2,3

ACCORDING TO THE SPECIFICATIONS OF EN12341: 2014

Standardized reference method for PM10 and PM2.5

 

Low volume air sampler for determination of mass concentration  PM10 or PM2.5 of suspension particulate matter, filter sample for laboratory determination.

Consists of a set of aspiration vane vacuum pump, suction head, filtration system and electronic system control assembled inside a polyester-fiberglass case outdoor suitable and  aluminum support frame that allows floor fixing. Operation, measurement and regulation flow controlled by a microprocessor and mass flow meter. Automatic control and constant maintenance of target rate with automatic compensation of the pressure drop for filter clogging or grid fluctuations. Continuous measurement of air temperature, sample temperature and atmospheric pressure. Interface user via LCD graphic display 240 x 128 dots and keyboard. Internal memory for storage of accessible data by RS232 / USB. 47mm Ø filter holder. Easy filter change by carrier holder. Holder valves closing by electromechanical system with filter position detector. Forced ventilation and heating.  PM10 or PM2,5 particles head built according to the specifications of EN 12341: 2014, with insulated tube connection and optional air cover.
