Claims

[Scope of Claim for Utility Model Registration] (1) A gas sensor that detects the concentration of a test gas generated from an object to be measured, a switch that operates upon contact with the object to be measured, and a gas reservoir that stores the test gas. a gas collection detection unit comprising a gas collection container having a part and an edge in close contact with the object to be measured; activated by the operation of the switch and validating the output of the gas sensor after a set time has elapsed; 1. A trace gas detection device comprising: a gas detector main body comprising: a timer for detecting the concentration of the gas to be detected; and a display section for displaying the concentration of the gas to be detected based on the output obtained from the gas sensor. (2) A gas sensor that detects the concentration of the test gas generated from the test object, a switch that operates when it comes into contact with the test object, a gas reservoir that stores the test gas, and a gas reservoir that is in close contact with the test object. a gas collection detection unit comprising a gas collection container having a close contact edge; a timer activated by the operation of the switch and validating the output of the gas sensor after a set time has elapsed; a central processing circuit that calculates the rate of increase in the output of the gas sensor over a certain period of time and estimates the true value of the gas concentration generated from the object to be measured; and a display that displays the obtained concentration of the gas to be detected. 1. A trace gas detection device comprising: a gas detector main body having a part; and;
