Description
Breathalyzer.
A type of tester designed to measure breath alcohol concentration in the human body. This device uses an advanced flat-surface alcohol sensor, which offers excellent sensitivity and reproducibility. The modern and portable design makes it more convenient for personal use.
If the alcohol content exceeds the preset limit level, this device will send an audio and visual alert to remind you of safety.

How to use
1. When using for the first time, prepare three 1.5V AAA batteries, remove the battery cover, install the batteries, and then replace the cover.
2. Press the power button.
3. "Preheat" 1 to 10 seconds, start the preheat countdown. Wait 10 seconds for preheating to complete.
4. After the preheating is complete, the device automatically enters a six-second countdown to detect puffs. Wait for the test results to appear.
PRE-HEATING
1. Press and hold the power button for 2 seconds. After the "dripping" sound, the tester's display will start.
2. The digital display will show "preheating" with a 10-second countdown. When the countdown reaches 0, preheating is complete.
TEST
1. After the "heating" phase is complete, enter the "blowing" state. The display will show a 10-second countdown. Blow air into the front of the device for three seconds, until the "dripping" sound indicates to stop blowing. Wait a few seconds for the measurement results to appear (if no air is blown, the result will be 0).

Measurement results
GREEN LIGHT: Under limit status: When the measurement is <0.3g/l, the green light is on.
YELLOW LIGHT: Alcohol consumption status: driving under the influence of alcohol: refers to the behavior of driving vehicles with a blood alcohol content ≥0.3 g/l.
YELLOW LIGHT on, alarm sounded.
RED LIGHT: drunk driving: refers to the behavior of driving a vehicle with a blood alcohol content ≥0.5 g/l.
The red light turns on and the alarm sounds rapidly.

Warnings
When the breathalyzer is first removed from the box, or if it hasn't been used for a long time, a large amount of gas and other impurities may adhere to the sensor. In this case, you need to press the power button several times to clean the breathalyzer by warming it up.
Do not use the product if it is damaged. Do not disassemble or alter the product without authorization. Do not immerse the product in water. It is not a toy. Keep out of reach of children. The appliance is not intended for use by persons with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they are supervised by an adult or have been given adequate instructions.
1. This product cannot determine whether you are driving under the influence of alcohol.
2. Judgments are based on general symptoms and criteria. Even with the same alcohol concentration, the degree of intoxication varies depending on physical conditions and individual differences.
3. Regardless of whether a breathalyzer is used or not, the relevant personnel of the manufacturer and retailers will not be responsible for drunk driving or any illegal behavior.
4. Alcohol takes about 20 minutes to be absorbed into the bloodstream through the digestive system. It is therefore recommended to measure alcohol 20 minutes after drinking. If measured immediately after drinking, the results may reflect the alcohol concentration, but not the blood alcohol level.
5. To obtain more accurate measurement results, the interval between two consecutive measurements should be more than three minutes.
6. Do not disassemble or wash the device. Store it in a place with few odors.
7. There is a certain margin of error between the measured result and the actual value when measuring at low power.
8. Keep away from direct sunlight and do not subject the device to excessive shock or vibration. Avoid heat sources.
