The Personalized Gurdian Against Drink Driving
1.Compact, accurate, reliable, smart looking and easy to use.
2.CA2000/S can be taken everywhere you go to help prevent drink driving and binge drinking.
3.CA2000/S uses same sophisticated oxide-semiconductor sensor as shown at right side and its test result is UNAFFECTED by COLA, COFFEE & SMOKING, which are commonly consumed with alcoholic beverage.
CA2000/S 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 semiconductive sensor (CA2000/S) reactive to alcohol substance only, which can be differentiated from the other semi-conductive sensor products (which are oftenaffected 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.



a) Highly reliable accuracy by the most sophisticated sensor :
CA2000/S adopts a highly-selective semiconductor sensor (reactive to only alcohol substance) designed by KAIST(Korea Advanced Institute of Science and Technology). CA2000/S is an unique breath tester adopting this most sophisticated technology of sensor.
b) Stable testing data : It allows you to get stable data for successive testing.
c) Digital type : It displays by 3 digits (0.xx% BAC/BRAC).
d) Wide detection range : 0.00 ~ 0.40% BAC or 0.00 ~ 2.00 BRAC.
e) Long-term stability : CA2000/S can analyzes very precisely even after long time of uses.
f) Compact & light weight hand-held device
g) Short warm-up & response Time :
After power on, less than 20sec. of warming up countdown (200 to 000) is needed to make it ready for testing. And, exhaling just for a few seconds will reach you to instantly read the testing numeric digits.
h) Longer life time : 3,000 times testing
i) Quick Recovery Time :
The sensor of CA2000/S can be purged in 30seconds for another time of testing. You don’t need to be too patient to do consecutive testing.
j) Sanitary Testing : CA2000/S includes 3pcs of mouthpiece for sanitary direct testing.
k) Alarm Sound :
If you are out of legal limit range, alarm sound will be automatically beeping. It could be customized depending on the countries.
l) Compact design and elegant outlook
