<p><P>PROBLEM TO BE SOLVED: To recognize a measured concentration of a detected gas intuitively. <P>SOLUTION: A gas detector comprises a display section 7 that optically detects a gas by using infrared absorption characteristics of a gas and displays the measured concentration of the gas that is detected.The display section 7 has a measured concentration level meter 7b1 that gradually level displays the measured concentration of the gas using the scale that a level range is equally divided to a plurality of steps.A user intuitively recognizes the measured concentration by the gradual level display of the measured concentration level meter 7b1. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
