Alcohol detector
Features
Sophisticated, highly- ive semiconductor sensor providing highly reliable accuracy
3 digits digital LCD display(0xx%bac)
Wide detection range:0.01~0.40%bac
Long-term stability
Short warm-up, response and recovery time
Audible alarm alerting user to positive test
Operation
Turn the switch on(pressit down). The buzzer sounds once. The detector will start the countdown 20 to 00 on the screen and finally display 0.00, indicating the sensor and circuit ready for test.
In this stage, if you don't blow to the breath pole within 70 seconds, the screen will automatically display off and the buzzer will sound discontinuously for turn-off.
Blow alcohol to the breath pole and test the level of your bac. The screen displays the level of bac. If the level on the screen is more than 0.05, the buzzer sounds alarm quickly. Otherwise, only the level is displayed on the screen. The screen will display "off" and the buzzer sounds discontinuously for turn-off after the test lasts for seventy seconds.
Note: If the tester has no response to the gas, you are kindly requested to take step 1 for two or three times repeatedly, for the tester needs a certain time for warming up.
For the successive test, take the above steps again.
The screen displaying "ee" indicates the sensor in error. The screen keeping flickering indicates low voltage.
Specifications
Sensor: Highly sensitive semiconductor alcohol sensor
Powered by two 1.5v batteries
Battery usage limit: Continuous use for 50 times
Test level:0.01%bac~0.40%bac
Warm-up time: Less than 20s
Response time: Less than 5s
Dimension:105*20*40(mm)precautions
For accurate result, do not smoke or eat anything for 20 minutes prior to testing yourself.
After drinking, it is recommended to test after 20 min.
It is because it takes 20 minutes approximately for alcohol to be absorbed into blood the digestive organs, and residual alcohol remaining in the mouth takes this long to dissipate.
Avoid testing under strong wind or in the closed room with contaminated air.
Recharge the battery or replace it when the low voltage comes on. Avoid blowing liquid into breath pipe.
