AlcoSense Excel Fuel Cell Breathalyzer
- Product Review (submitted on 10 January 2018):
- As with any scientific instrument I need to trust the detail it provides, difficult to double check however it seems to do exactly as described. For me it isn’t the night I have been drinking, that’s a given, but when exactly the next day has enough cleared to be safe. Will keep it handy and use it occasionally. Note that it needs to be sent off for recalibration after a year which is a pain, would be better to take it in somewhere.
