As for quality evaluation of paper records, it is very important to measure acidity and moisture in paper. In the case important paper records, it should be measured directly in field. But ISO standard analytical method would be limited to measure directly in field for quality evaluation of paper records until now. Therefore it could be to use mobile small NIR spectrometer for being analyzed by direct and non-invasive method in field. The wavelength range of small spectrometer has from 900 to 1700 nm, and the surface of paper could be measured by diffused reflected optical fiber probe. Thus, the acidity and moisture could be analyzed on the paper record with from 1970 to 2003. As the result, it could be confirmed to have each more than 0.9 as the correlation of acidity and moisture. Thus, it will be possible to develope the evaluation system of paper record with mobile small NIR spectrometer and optical fiber by the result.
