Abstract
PURPOSE: To carry out the reading of the detection command easily by using a non- detecting zone forming means for preventing the detecting command with respect to level lower than a predetermined gas concentration level.
CONSTITUTION: An element 2 is connected in series with a variable resistor 4 for adjusting a detecting sensitivity of a gas sensor 1 and connected to an operating voltage source 5 through a switch 6. Voltage of the voltage source 5 converts the change of resistance value of the gas sensor 1 into an electric signal as voltage between terminals of the variable resistor 4. Between the terminals of the resistor 4, a voltmeter 6 connected in series with a non-detecting means 7 forming a not detected blind zone is inserted. By this non-detecting means 7, in the case of below predetermined voltage, meter pointer indicates zero.
