2. The Personalized Gurdian Against  Drink Driving

1.Compact, accurate, reliable, smart  looking and easy to use.
2.CA-2000 can be taken everywhere you go to help prevent  drink driving and binge drinking.
3.CA-2000 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.

CA-2000 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 (CA-2000) 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.

3. How To Use :


1)Turn on the PWR On/Off  switch
  - Soon after the power on, CA2000 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 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/ 0.05mg/L BRAC), it may not be activated. However, it shows still 0.00% and you're said to be in  safe range.
3)Then, after 3.5 seconds, 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% / 0.25 mg/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
