Der Formaldehyd-Filterwechsel-Indikator Low-Flow-Filters ist ein kolorimetrischer Indikator, der die S\u00e4ttigung und Ersch\u00f6pfung der hplc-Abfallbeh\u00e4lterfilter anzeigt. Der Indikator ist ein zuverl\u00e4ssiges und kosteneffektives Mittel zum Schutz vor Formaldehydd\u00e4mpfen. Der Indikator verf\u00e4rbt sich von gelblich-braun \u00fcber dunkelbraun bis violett, wenn die Filter mit Formaldehyd ges\u00e4ttigt sind.<\/p>\n

Acrolein und Aldehyde reagieren mit ungef\u00e4hr der gleichen Empfindlichkeit. Andere Interferenzen sind nicht bekannt. Sie k\u00f6nnen den Indikator einfach in den Filterauslass einsetzen (ein Schaumstoffadapter f\u00fcr geschlossene Poren ist erforderlich; bitte kontaktieren Sie uns f\u00fcr weitere Informationen). Der BTI LFF arbeitet bei Temperaturen von 4o<\/sup>C to 32o<\/sup>C (39o<\/sup>F to 89.6o<\/sup>F) und Luftfeuchtigkeiten von 5% RH bis 85%RH. Der Indikator ist 3,0 Zoll hoch, hat einen Durchmesser von 3\/8 Zoll und Sie k\u00f6nnen den hellen, leuchtenden Farbwechsel aus allen Richtungen beobachten. Das einzigartige Design des Indikators verhindert jegliche Farbver\u00e4nderung aufgrund von Verunreinigungen in der Umgebung. Er \u00e4ndert seine Farbe nur, wenn der Filter ges\u00e4ttigt ist. Der Indikator hat eine verl\u00e4ngerte Lebensdauer von 1 Jahr plus 14 Monate Lagerf\u00e4higkeit.<\/p>\n
