Introduction: 

Thank you for purchasing our ACE AFM-5 Breathalyzer. It measu-
res alcohol concentration in human breath using an electrochemi-
cal sensor and calculates the blood alcohol level. The test results 
are very reliable and have a tolerance of +/- 0.050‰ (per mill) 
with reference to 1.0‰. The device must only be used pursuant 
to the instructions mentioned in this manual.
 
 

Short description:  

The ACE AFM-5 Breathalyzer is an easy-to-use alcohol tester 
with an electrochemical sensor. It is used in combination with a 
smartphone (only iOS and Android system possible / no tablets). 
Before performing the test you have to download the “

Alcofind“ 

app from the App Store (iOS) or from Google Play (Android) 
and install the app on your smartphone. The test result can be 
interpreted 1:1 (so if the shown test result. is, e.g., 0.360, then 
this means 0.360 per mill). ‰ (per mill) = measurement unit in the 
EU, in the App “

Alcofind“ you can change the measurement unit 

into % BAC (USA) or into mg/L (UK).

The fuel cell sensor inside the ACE AFM-5 Breathalyzer can be 
calibrated. For a calibration service you can send the device to 
ACE Instruments (see www.ace-instruments.net). For each breath 
test a new mouthpiece is required.
