BACtrack S75 Pro BreathalyzerThe BACtrack S75 Pro Breathalyzer is another solid option from BACtrack line of professional grade breathalyzers.  This breathalyzer uses a fuel cell technology that it enables it to be extremely accurate and comparable to some of the units that the police use.  This technology also allows it to be used in medical testing as well.  Most of the cheaper breathalyzers on the market use a semiconductor technology that’s prone to inaccuracies.  The semiconductor breathalyzers won’t give you a consistent reading back to back like a fuel cell technology breathalyzer will.  They also tend to give inaccurate readings to people with diabetes or those on a lower calorie diet.

Compared To The Select S80

BACtrack also has the Select S80 Professional model which is a little bit more expensive than the S75.  However, to be fair, I honestly can’t find much of a difference other than design.  So, you might as well save some money and pick this one up.

Front Facing Mouthpiece Is Awesome

What I like about the BACtrack S75 Pro is its sleek design and front facing mouth piece as compared to other breathalyzers with the mouthpiece on the side.  It allows you to watch the display as it counts down so you can blow into it.  This eliminates having to twist or turn the breathalyzer when it hits zero.   You have to be able to blow quickly enough for a more accurate reading and twisting the breathalyzer will just delay you.

Here’s what customers are saying about the BACtrack S75 Pro

As of right now, there’s 32 reviews on and it has an average rating of 4/5 stars, which is pretty good!  People like that it’s a professional breathalyzer that they can really trust.  One user has a friend that’s a police officer and ran a test between his unit and her S75 Pro and the results we’re nearly identical.

Another reviewer bought this model because DUI’s were on the rise in his city. A lot of people were getting arrested after just having a beer or two.  So, he wanted to make sure that he bought a fairly accurate one that wasn’t going to cost him too much.  He feels reassured that he can take a few tests within a few minutes of each other where each test shows a similar result.

Some people have issues with the rate they have to blow.  You may experience a “flow” error rather easily while others don’t.  It seems like you have to find the sweet spot sometimes.

We like the BACtrack S75 Pro Breathalyzer and feel comfortable recommending it.
