Method and device for analysis with color identification test paper

摘要: A method and apparatus are disclosed for an analyzer which measures concentration of a liquid specimen by monitoring the coloration test paper is either dipped into or otherwise painted with it. In method, inner stray rays produced light source do not reach experimentally monitored, so that effect such upon accuracy analysis eliminated. Additionally, relating relative reflectivity to disclosed, in calibration curve modeled as section hyperbola. apparatus, microcomputer performs evaluation detection compensation various sources instrumental error takes place electronically.
