Yes, it is a equipment which often used to test whether the drivers are alcohol excess.In addition, it also can be used in government offices or other enterprises institutions, may also play a supervisory role. With this alcohol tester, it’s easy to create a good working environment. New gas alcohol concentration detection technology has become an integral part of security market.

May you have used this alcohol tester before, but do you know what’s its detection principle? Let me tell you: when the N-type conductive oxide expose in the atmosphere, due to the adsorption of oxygen, so will reduce the number of its internal electronic and resistance increases.Thereafter if the atmosphere there are some specific reducing gas, it will adsorb oxygen reaction, so that the increase in the number of electrons within the oxide, then the resistance which lead oxide will be reduced. The sensor of semiconductor oxide will analyze the gas concentration through the changes in resistance.
