General Introduction

AT-S350 dual display breath alcohol tester is a kind of tester designed to measure concentration result of the breathed alcohol in the human body. This device adopts advanced MEMS semiconductor alcohol sensor which has excellent sensitivity and reproducibility. Fashion and portable design make it more convenient for personal use. When the alcohol content exceeds the preset limited level, this device would send an audio warning to remind your safety.

3. Smart MCU control
4. Direct testing process LCD indication
5. LCD indication, backup lamp
6. Portable design
7. No touch health design
8. Audio warning beyond pre-set limit
9. Power saving design, low battery indication
10. Clock with 12/24 formats with alarm function
11. Design patented

How To use the alcohol tester

Warm up

1. Press the power button and hold it,  the alcohol tester LCD will turn on with one beep sound.

2. The “warm up” symbol is displayed,  and the 18 to o countdown is started that indicate the tester is in warm-up mode.

Note

If fist warm-up is defeated,  the tester will be reset automatically and warm up again.

It always has a large number of gas & impurity adsorbed on the surface of alcohol sensor,  when first time taking out the tester from the packaging,  or after long time no using for the tester,  you should repress the power button and retry several times if possible.

Test

1. The “Blow” symbol is displayed when warm-up is succeed,  and the 10 to 0 countdown is started that indicate the tester is in testing mode.

2. After you hear one beep sound,  near and blow into the breath inhaler steadily,  stop after you hear another beep sound.

3. Read the test result from the alcohol tester LCD

4. There will be beep alert when the alcohol concentration is the level:

          Over & equal 0.05%BAC(0.5g/l)

Auto power off

1. After the result be display for about 15 seconds,  the “OFF” symbol will appear for 2-3 seconds and the alcohol tester be turned off

2. If warm-up is defeated,  the tester will automatically turned off.

3. If no blow into the breath inhaler at the test mode,  the LCD will display “0.00” value.
