Breathalyzers can determine blood alcohol content from a sample of breath. Usually, only cops on patrol carry these. But it can be useful to have one around the house, especially if you are medically required to measure your own BAC.
You can buy a budget breathalyzer for less than $40. The best cheap breathalyzer I have, the Greenwon Professional Breathalyzer, cost me only a few bucks.

Tips for Buying a Good Budget Breathalyzer
Here’s what you should keep in mind when shopping for cheap breathalyzers:
Don’t expect high levels of accuracy. Budget breathalyzers are only good at giving approximate values that are closest to the accurate numbers. Don’t rely too much on the numbers you get. When shopping, look for breathalyzers designed using police-grade technology to get the best results.
Buy a compact breathalyzer as they are very easy to carry around. Most budget breathalyzers are small and come in key chains for carrying convenience.
Read instructions carefully. Check for things like waiting time between tests and waiting time after turning on before purchasing a device.
There are energy saving options for budget breathalyzers. Some quickly drain the batteries. Others have features like auto off to save battery power. Choose one of these to not waste money buying new batteries.
Buy a newly released budget breathalyzer if you can. Breath testing technology has vastly improved in recent years so the newer products are more accurate than older ones.
