METHOD AND APPARATUS FOR MEASURING CONCENTRATION OF NITROGEN DIOXIDE |
| 摘要 |
PROBLEM TO BE SOLVED: To measure with higher accuracy and to miniaturize an apparatus while reducing cost by dispensing with a filter for eliminating short wavelength components. SOLUTION: The apparatus for measuring the concentration of nitrogen dioxide by performing a difference absorption spectrometry uses a white light emission diode 1 as a light source.
