Precautions when detecting alcohol gas

In the context of the All Gas sensor's standard response state, the sensor reacts to ethanol (alcohol) gas by initiating a chemical reaction on the SE (sensing electrode) upon the gas's entry. The CE (counter electrode) and RE (reference electrode) do not come into contact with the ethanol gas. When an appropriate amount of ethanol gas enters, it is fully reacted on the SE working electrode, resulting in the sensor operating at its optimal measurement state. The reaction of ethanol on this sensor is positive, generating a positive output signal.In the case of high-concentration ethanol or when pressurized gas is directed towards the inlet, a significant amount of ethanol gas may enter the sensor. The SE working electrode may not be able to react to all of it within a short period, or due to pressure, the gas may enter the RE reference electrode, causing the signal to switch from positive to negative. If the concentration exceeds 1500 ppm and continuous exposure lasts for 2 hours, a recovery period of at least 10 hours is required before the sensor can resume normal measurement.
