SITITEK CA20F — is a personal breathalyzer with an electrochemical sensor and high measurement accuracy. Conducts testing by contact, has an audible alarm of increased blood alcohol concentration. The device is powered by a battery "Krona", which is enough for 500 tests. It is provided with a convenient plastic case.

Provides high accuracy and reliability of measurements Through the use of such a sensor, measurements of the alcohol concentration in the exhalation are carried out with a small error. Unlike semiconductor sensors, an electrochemical sensor is much more selective for alcohol vapors (the possibility of the influence of external factors on the test results is excluded), consumes less energy and is suitable for multiple tests during the day. He also rarely needs calibrations - every six months or after 500 tests. |

To start testing, just press one button After pressing a single button below the screen, the device will begin self-testing and preparation for measurement. After a short time, the message "blow" will light up on the screen, meaning that it’s time to start testing directly. Insert the mouthpiece into the connector on the instrument case, inhale deeply and start breathing out air until the beep sounds, indicating that the breathalyzer is engaged in the analysis of the sample. After data processing (no more than 35 seconds), the result will be shown on the display. |

The accuracy of the test results depends directly on the correct expiration. The SITITEK CA20F controls the completeness of the expiration in the mouthpiece automatically, avoiding false measurements. |
The test results are displayed on the large LCD screen, equipped with a bright backlight, thanks to which the user can see the readings even in complete darkness. |
Thanks to the miniature design and the light weight, you can carry the device at any time. It does not take up much space in a man's purse or handbag. |
