More info

Electrochemical breathalyser AL-9000 offers high precision readings

The AL-9000 alcotester is a construction based on an electrochemical and very precise sensor, such as those used in specialized breathalysers, offering sensitivity similar to professional police devices.


A customer choosing this product can be sure of its high quality. The displayed values reflect real and precise blood alcohol concentration. A number of inferior semiconductor breathalysers detect not only the breath alcohol content - the results they provide may be distorted by smoking cigarettes, or even chewing mint gum! The AL-9000 model eliminates these drawbacks and ensures the stability and reproducibility of the results.

The breathalyser has many additional features to facilitate its use. The ability to perform tests at intervals of 10 seconds is ideal when you need to monitor the sobriety of employees. It saves our time and enables multiple measurements, one after another. The indication quality is also supported by air flow control function, which provides an adequate flow of air through your sample. In case of police control, you can be confident about the result of the breath test.

What is also important is the ability to store past results and generate lists in Excel spreadsheets after connecting the breathalyser to a computer via mini USB output.

Due to the solid housing made of aluminium and the highest quality durable plastic, AL-9000 breathalyser can be used for a very long time by both individual customers and companies.
