Immission Line 2.221.01 Atmospheric PMx particles monitor SWAM 5A Dual Channel Monitor SWAM 5A Dual Channel Monitor is an automatic sampling and mass measurement system of suspended atmospheric particulate matter, working with two independent sampling lines. The sample is accumulated on a filter device and its mass is determined using an innovative technique based on the ß attenuation method. SWAM 5A Dual Channel Monitor allows a high quality standard monitoring of the average mass concentrations trend of two PMx particulate fractions (for example PM10 and PM2,5). Moreover, the samples accumulation on filter membranes allows the chemical characterization of the particulate matter and the direct gravimetric determination of their mass. SWAM 5A Dual Channel Monitor can also be used for the metrological evaluations of the particulate matter sampling and mass measurement systems. SWAM Dual Channel Monitor can be used as a reference sampler. Infact, the instrument is certified TÜV and MCERTS, in compliance with EN12341 and EN14907. Moreover, the instrument can sample the suspended particulate matter (PM10, PM2.5) in compliance with the technical instructions described in US EPA regulations about: · PM10 sampling, using the US EPA 40 CFR part 50 1 m3/h sampling inlet · PM2.5 sampling, using the US EPA 40 CFR part 50 1 m3/h sampling inlet with WINS PM2.5 impactor. Ed. 0 11/11 - Technical specifications may change without previous warning · In compliance with national and international regulations regarding air quality control for suspended particulate matter · High quality standard of representative suspended PMx sampling phase · High quality standard of the PMx samples mass determination phase · Innovative implementation of the ß technique, covered by International Patent, that uses a unique integral source detector system and auxiliary measures on “spy filters” · Long working autonomy without operator’s intervention, thanks to the automatic management of max.72 filter membranes · Complete operation management via GSM Modem · Automatic management of the sampling cycles (real-time acquisition of the parameters and relative quality controls) Approved Product Data Immission Line 2.221.01 TECORA - Headquarter: 211-215 rue la Fontaine, 94134 Fontenay Sous Bois Cedex - FRANCE.
