Therefore, the act of measuring itself does not influence the temperature of the object. The name pyranometer stems from the Greek words πῦρ (pyr), meaning "fire", and ἄνω (ano), meaning "above, sky". However, in some cases the choice of a ratio pyrometer (2-channel pyrometer) is required, which simultaneously measures in two spectral ranges and determines the temperature by quotient formation.
