Alcotester

The breathalyzers we sell come with electrochemical sensors, so their accuracy is quite accurate. The breathalyzers on sale are semi-professional, so you get a standards-compliant breathalyzer regardless of its price. The key to choosing an breathalyzer is how often and where you use it.
