Bayanan samfurin
MQ135B Air gurɓataccen gas firikwensin amfani da gas m kayan ne tin dioxide (SnO2) tare da ƙananan lantarki conductivity a cikin iska mai tsabta. Lokacin da gas na'urar firikwensin ke da gas mai gurɓataccen yanayi, na'urar firikwensin tana ƙaruwa tare da ƙaruwar yawan gas mai gurɓataccen yanayi a cikin iska. Amfani da kewayawa mai sauƙi zai iya canza canje-canje na wayoyin lantarki zuwa siginar fitarwa da ta dace da wannan yawan gas.
MQ135B iska gurɓataccen gas firikwensin ne high hankali ga ammonia, sulfide, benzene tururi, da kuma m sa ido kan hayaki da sauran cutarwa gas. Wannan firikwensin yana iya gano nau'ikan iskar gas masu cutarwa da yawa kuma yana da ƙarancin farashi don aikace-aikace da yawa.
