High Volume Air Sampler SNOWAWEDTE S ENP gt A FINLAND High Volume Air Sampler 2 SNOW JL 900 SNOW WHITE is high volume air sampler It s ment for hard continuous outdoor use The baseframe structure is so strong that whole unit can easily be installed even on four rocks if neccessary For installation just connect the mains cord and start sampling SNOW WHITE is very easy to use and in the designing work users opinions were listened carefully Pump control can be made with frequency converter thus giving possibility for changing volume flow Panel meters are microprocessor based and they do all neccessary calculations that you need total volume and total time Air volume is calculated from pressure difference over calibrated orifice also in carbon line Carbon line is equipped with valve so it can be closed totally Pressure drop when using Whatman GF A glass fiber filter is c 10 000 Pascals Pumps maximum efficiency is 20 000 Pascals so there is lots of reserve power to hold volume flow stable even when filter gets filled Filter cassette which is made of aluminium can be loaded already in laboratory thus avoiding problems with rain and wind outside Pipes and supporting frames are made of stainless steel which is electrochemically polished after fabrication GRP glass reinforced plastic covers are thick enough to withstand even small flying stones or hammering GM probes can be in
