Abstract

PURPOSE: To simplify the level adjustment while enabling the control of ventilating fans according to the concentration of polluted gas.
CONSTITUTION: A sensor 1 employs a semiconductor of metal oxide. The level adjustment 12 in the clean air is made by visual observation of the lighting or extinguishing position as prescribed on an indicator 10 or the specified position on the ammeter. When the concentration of polluted gas exceeds the level observed at the adjustment by more than a given value or a given range, the control output 11 is provided.
