CA-2000S 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, which can be differentiated from the other semi-conductive sensor products (which are often affected by 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.

1) Highly reliable accuracy by the most sophisticated sensor

CA-2000S adapts a highly-selective semiconductor sensor(reactive to alcohol substance) designed by KAIST(Korea Advanced Institute of Science and Technology). CA-2000S is an unique breath tester adopting this most sophisticated technology of sensor.

2) Stable testing data

It allows you to get stable data for successive testing.   

3) Digital type ; It displays by 3 digits (0.xx% BAC/BrAC).

4) Wide detection range : 0.00 - 0.40% BAC

5) Long-term stability

CA-2000S can analyzes very precisely even after long time of uses.

6) Compact & light weight hand-held device

7) 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.  

8) Longer life time : 3,000 times testing

9) Quick Recovery Time

 The sensor of CA-2000S can be purged in 30seconds for another time of testing. You  don't need to be too patient to do consecutive testing.

10) Power

9V Alkaline battery

11) Sanitary Testing

CA-2000S includes 3pcs of mouthpiece for sanitary direct testing.

12) Alarm Sound

If you are out of legal limit range, alarm sound will be automatically beeping. It could be customized depending on the countries.

13) Compact design and anaesthetic outlook

1) Turn on the PWR On/Off switch

Soon after the power on, CA-2000S will start the countdown 200 to 000 on the display window. - It is a "Warm-up" process to make the sensor and circuit be ready for testing.

2) When you hear beep sound & green lighting is on READY, please blow into for 3 seconds till you would hear another time of "Beep" sound.

N.B. : 1. In this stage, if you don't blow within 30 seconds, it automatically shows OFF display for turn-off

2. In case you drink quite a little (if actual concentration would be below 0.01% BAC/0.05 mg/lBrAC), it may not be activated. However, it shows still 0.00% and you're said to be in safe range.

3) Then, the test result (BAC or BrAC)  will be displayed by 3 digits for 15 seconds  at the same time both READY and WARN lamps are flickering.

N.B. : 1. If the BAC / BrAC data would be over 0.05% / 0.25mg/l(default setting) respectively, red  WARN lamp will be flickering along with "Alarm" sound.

2. The "Alarm" level is adjustable pursuant to the local legal limit.

4) Finally, it shows "OFF" for turn-off.

5) For the successive testing, try again from No.1 to No. 3.

After drinking, it is recommended to test after 30 min. It is because it takes 30 min. approximately for alcohol to be absorbed into blood from the digestive organs. And residual alcohol remaining in the mouth may cause inaccurate data.
To avoid testing under strong wind or in the closed room with contaminated air.
When the "BAT LOW "lamp is lighting on, it's advisable to replace 9V alkaline battery.
To attain more accurate data, please repeat testing about 3 times.
