PRODUCT SYNOPSIS

*
Breath Analyer is an unique & highly-sophisticated alcohol analyzer utilizing the variation of electrical property value of the oxide-semiconductor when the alcohol substance is detected. And, with the development of new ceramic material combined with relevant catalyst, it can selectively analyze the alcohol concentration to the ppm unit existing in the human breath. Our laboratory made it in developing the highly-selective semi-conductive sensor reactive to alcohol substance only, which can be differentiated from the other semi-conductive sensor products (which are often affected by the other substances like smokes and smells of food). Furthermore, it did improve to the large extent the standby, response & recovery time which could be crucial in measuring gas concentration.
 
*
Detection mechanism of our unique semi-conductive sensor When the oxide having the property of n-type conductivity is open to the atmosphere, it decreases the number of electron affecting on electrical property by the adsorbed oxygen and results in increasing the resistance. And, afterwards, if the specific gas (reducing gas) exists in the atmosphere, it reacts with the adsorbed oxygen and increase the electron in the oxide, resulting in decreasing the resistance. So to speak, the electrical property of the oxide is getting changed when a specific gas is exposed from the outside and our sensor can analyze the gas concentration from the variation of quantity.
