Does this device ever have to be calibrated for accurate BAC readings?

Sean, I have purchased many BAC testers over the years and have yet to find one that does not require calibration. Because they have a sensor built into them, over time or heavy use, the sensor will need to be recalibrated. The Breathometer says calibration is recommended after 250 uses which is in line with others in the market (typical range from other products is usually 100-300 uses). A nice feature here is that there is a test count in the app allowing you to keep track.

Yes! According to Breathometer support "Our device needs to be calibrated after 9 months or 250 uses. To find more information, please visit:https://www.breathometer.com/calibration&quot; There is a $20 charge for factory recalibration.

No it doesn't need to be calibrated. I would say it's a guide. We had fun over Christmas testing everyone from people who drank nothing to a person that did a shot before testing. It seemed pretty accurate.

If by "calibrate" you mean manually set the thermometer to a specific temperature, then the answer is "no". On the other hand, if you mean by "calibrate" to check out against a preset temperature, then "yes" you could do this..e.g., immersing the probe in an ice bath.

You know Tony, I'm not sure how it's calibrated from the factory but I compared the Raytek to a thermometer when checking out the temp of a hot cup of water. They were almost exact. For my home use purposes, that is all I need. I guess the manufacturer can answer how exact calibrated it comes from the factory. But out of the box, it appears to be very close.

Yes, you can find several calculators online to compensate for the alcohol after fermentation. I have a refractometer and a hydrometer and I used an online calculator that wasn't accurate for this use. Plus it uses a much smaller sampling size compared to a hydrometer.

Hi Brent, I've just opened one of them up, and the answer is no. There is no off set or gain potentiometer that would allow a calibration. I have been using temperature devices for years, and I have to have them calibrated annually. I have never had a 0.5C thermocouple be out out of spec--only an RTD one that goes to hundredths of a degree. They typically do not go bad or drift (unless damaged). Regards, Daryl

I don't think you can calibrate it. I haven't seen anything on the device or the app that lets you do it. Myself and 3 other people I know use it on a regular basis and have never had this issue. You might have a defective unit.

The only calibration I have seen happens during each power-on. The directions ask for a vial of clear pool water and it self calibrates.

This is the most accurate device! It is as accurate as my state issued alcohol device in my car. Well worth the money

I wish I could sincerely answer your question. This device has not been the best so far. Constant calibration and off results. I would suggest investing a little bit more money on a better scale.

I checked the users guide and do not see any information about calibration of the unit. There is a support number you can call.

Yes because the device calibrates it to match a standard calibration. So what you see is what other's see when they have also calibrated. Therefore it will calibrate them all to the same standard.

Interesting question. You might try the Taylor site. My past experience has been that the calibration isn't correct if it is replaced. My friend upgraded to this unit when his failed. I will probably follow suit. http://www.amazon.com/gp/product/B00EHNH3JC/ref=oh_details_o05_s00_i00?ie=UTF8&psc=1

I ordered one of these and was concerned that it was not reading accurately, and the company replaced it. Neither device came with a calibration certificate.

I have had no problems with mine. Accurate as far as I have been able to determine.

I did not calibrate it except to test against another thermometer. It was right on. No adjusting is possible to the reading.

I use this for measuring my OG and FG of my beers. My friend who got me into brewing and works for a national beer supply distributor also uses this. You can calibrate this with distilled water. Does that mean it's accurate? I have to think so. I have not compared the results of this against my hydrometer, but if they were off I'm not sure which would be more accurate.

Hi, I checked the manual it does not list calibration procedures. This is an inexpensive unit and when it goes bad it is time for a new one. I had their previous model for 5 years before it needed to be replaced. Good luck
