Title:
GAS MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2015232532
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gas measuring device capable of determining a plurality of kinds of gases and detecting its concentration by the same detector paper.SOLUTION: A gas measuring device comprises: means for detecting the optical concentration by wavelengths of different reaction marks of detector paper carrying silver salt which generates the reaction mark of silver colloid in reaction to at least a plurality of kinds of measured gases; gas determination means for specifying the kind of gases based on a ratio of the optical concentration of respective wavelengths of the same reaction mark; and concentration computing means for calculating the gas concentration based on the chemical concentration.
