Abstract

Jonizacyjny detektor nanoobiektów w powietrzu, charakteryzuje się tym, że zawiera komorę pomiarową (15) z jonizacyjnym czujnikiem dymu z elektrodą pływającą, przy czym powietrze do komory pomiarowej (15) zasysane jest przez pompę próżniową (17) zainstalowaną za komorą pomiarową (15), przy czym zasysane powietrze jest doprowadzane do komory pomiarowej (15) z impaktora (11) poprzez dwa przewody powietrza: pierwszy przewód zawierający filtr HEPA (12) i zawór zwrotny (13) oraz drugi przewód zawierający elektrozawór (14).The ionization detector of nano-objects in the air is characterized by the fact that it contains a measuring chamber (15) with an ionization smoke sensor with a floating electrode, and the air into the measuring chamber (15) is sucked by a vacuum pump (17) installed behind the measuring chamber (15), wherein the sucked air is supplied to the measuring chamber (15) from the impactor (11) through two air conduits: the first conduit containing a HEPA filter (12) and a non-return valve (13) and the second conduit containing a solenoid valve (14).
