Chinese man fails breathalyser on eating durian fruit

So easily fixed then
'Have you eaten durian fruit in the last five minutes sir' If it's a yes delay the test by 5 minutes!

One sip of alcohol just before a breath test will put you way over, which is why the UK Police have to wait 20 minutes after you say you last had a drink (so if worried say you've just had a drink to waste 20 minutes of processing time!).

Also, breathing very recently consumed alcohol into a breathalyser can damage the unit.

Really, why is that (just asking out of curiosity)?

Not really sure. I'm basing my remark on the fact that (even expensive) consumer fuel-cell breathalysers, apparently using the same technology as police units, can be damaged this way, and extrapolating this to the likes of Draegar units.

A couple of examples:

Performing a breath test less than 10 minutes after drinking risks blowing high levels of alcohol directly from your mouth into the system which could permanently damage the sensor.

Always wait at least 15 minutes after drinking or smoking (or you can damage the sensor)
