Cóip statach de shonraí a easpórtáiltear ó IATE ó am go chéile atá sa chnuasach seo. Níor cheart glacadh leis gurb ionann i gcónaí an t-eolas a thugtar faoi iontráil anseo agus a bhfuil sa leagan reatha den iontráil ar IATE. Is féidir an leagan reatha sin a cheadú ach cliceáil ar an nasc atá ar thaobh na láimhe deise ag barr gach iontrála. Breis eolais »

    Sainmhíniú technique for measuring the volumetric concentration of carbon oxides in a gas sample, by shining an infra-red beam through a sample cell (containing CO or CO2, and measuring the amount of infra-red absorbed by the sample at the set wavelength Tagairt "COM-EN, based on:Cambustion > Operating Principle. http://www.cambustion.com/products/ndir500/operating-principle [2.2.2015]"
    Nóta NDIR measurement is based on the principle that each constituent gas in a sample will absorb some infra red at a particular frequency.
