I would say no. It wouldn't need "recharging" or "recalibration". There would nothing wrong with the device and electrically there would be no isssue. Rather, the device would "run dry" and need more chemical. Imagine they could sell "back-up cartridges that could replenish the tag molecule in the device. It would likely be expensive... if the "tag molecule" is an expensive chemical, or hard to produce. If the "tag molecule" is a cheap and widely available chemical, then they could sell these replenishing cartridges for cheap.

This is my guess. But I should also note, that they may only need super small quantities of this chemical for each detection, and thus technically could be good for thousands of breaths. It is hard to say.

Another factor to consider would be the lifespan of the chemical. Not all chemicals stay preserved in their original form forever. That's the biggest issue I see with their device. If the chemical starts to deteriorate, then basically the device is less sensitive. So if a police department has these things in a moisture environment in the back of a squad car every day and the chemical degrades over a year span, then all the sudden people who are blowing into the device are not getting detected because the tag molecule has gone to shit. They need lengthy clinical trials in all kinds of environments to know this stuff. A lot of the chemical qualities will already be known though, as "time to degradation" is a characteristic unique to the chemical and perhaps this is a really stable chemical to oxygen and moisture. It needs to be air stable, because... it is interacting with breath.
