These are the standard size water collector jars for EPA pattern PM10 inlets, as used by most inlet manufacturers for many years. Keep some spare jars on hand, especially if you use these in cold regions, because they sometimes break when fine snow melts into the water trap and then refreezes. The jars are 3 inch tall with 2 3/8 inch (60mm) diameter necks.
