    - Smart Fuel Cell Sensor Professional Use Breathalyzer

CA20FS Smart fuel cell sensor alcohol tester is the gold standard of hand held alcohol testers for both personal and professional use. The breath is directed into a fuel cell sensor with dual platinum electrodes where alcohol oxidized and generates electrical current. By precisely measuring this current, alcohol tester gives very accurate measure. The fuel cell sensor is specific only for alcohol and does not respond to acetone, ketone or other substances which can be found in human breath. The CA20FS gives high accuracy and wide detection range up to 4.00‰. The tester is equipped with an advance temperature function to help you operate it in an optimal temperature range.

  • - Benefits of Fuel Cell Sensors

Fuel Cell sensors are the latest advancements in digital alcohol testing. Designed to be more accurate as semi-conductor sensors, fuel cells are the gold standard when testing BAC. An increase in durability leads the CA20FS to have an extended life before needing calibration. A less frequent service and maintenance schedule, lowers the overall cost of ownership. In addition, the CA20FS will not detect a false positive for individuals on a low carb diet or diabetic.

  • - Alcohol Test

Easy to use – simply insert mouthpiece and begin testing immediately.Push the ON/OFF power switch.The tester will show "ON" together with a sound and starts countdown which will be taken about 15~35 seconds. This warm-up process prepare the sensor and circuit for testing. After display will show "BLO" and you will hear beep sound. Blow steadily into the mouthpiece until you will hear beep sound again. After completion of analysis for about 3~22 seconds, the test result will be displayed by 3 digits for 20 seconds along with beep sound. If data will be over 0.500‰, the display will show the result and "Warn" signal (RedLEd) will be displayed with alarm sound. Finally the unit will show "OFF" and turn off automatically with a sound.
