Compact, accurate, reliable, smart looking and easy to use. 2. HD-CA-2000 can be taken everywhere you go to help prevent Drink driving and binge drinking. 3. HD-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. HD-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 (HD-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. 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. 3. Finally, it shows OFF for turn-off. 4. For the successive testing, try again from No.1 to No.3 We are looking for dealer, distributor, importer to represent our products in your state or city.
