<p>PROBLEM TO BE SOLVED: To provide an industrial pretreatment device which enables a user to surely avert a reduction reaction, to grasp the transition of consumption with lapse of time, to easily and surely grasp the timing for replacing industrial pretreatment agents and to detect so-called current transformation. SOLUTION: The industrial pretreatment device passes harmful gas along an axial direction of a cylindrical container 11 containing the industrial pretreatment agents 15, allows the gas to pass through the industrial pretreatment agents 15 and converts the harmful gas to harmless gas or easily treatable gas by a chemical reaction. The above device is provided with temperature sensors T1 to Tw disposed at >=3 points along the flow direction of the harmful gas and means 18 for scanning the temperature measurement by the temperature sensors T1 to Tw.</p> |
