5. Questions on Calibration.

We are currently looking into providing calibration services for our breathalyzers. We are not able to provide calibration services at the moment. 

If you would like to be informed when we start to provide that service, please subscribe to our newsletter or send us an email at contact@precisionbreathalyzer.com

 

If you own a DA7000, AL7000 or a AL6000, they have a replaceable sensor feature and the replaceable sensors can be purchased here

 

While many websites recommend a calibration every 200 tests (for semiconductor models) or 500 tests (for fuel cell models), we have tested our breathalyzers by using them ourselves and found that they are accurate even up to a year. We, users of breathalyzers ourselves, use it for over a year at a frequency of 1 or 2 tests a week. It is important that the breathalyzers are used according to the guidelines within the manual, the next section of the faq talks about the guidelines of proper use. While this is not a guarantee that the breathalyzers we sell last as long as we experienced them to be, we believe in honesty and maximising value for our customers.


6. How many tests does a sensor last? Guidelines to maintain a breathalyzer.

While many websites recommends a calibration every 200 tests (for a semiconductor mode)l or 500 tests (for a fuel cell model). We have tested all our breathalyzers by using them ourselves and found that they are accurate even up to a year. We, users of breathalyzers ourselves, the THEM for over a year at a frequency of 1 or 2 tests a week. It is important that the breathalyzers are used according to the guidelines within the manual - the next section of the FAQ talks about the guidelines of proper use. While this is not a guarantee that the breathalyzers we sell will last as long as we experienced them to be, we believe in honesty and maximising value for our customers.

 

If you own a DA7000 or a AL7000, they have a replaceable sensor feature and the replaceable sensors can be purchased here.

 

Guidelines to prolong the life of a breathalyzer:

- Cigarette smoke particles may destroy the sensor. Wait 20 minutes after smoking before using the breathalyzer.

- Food particles and saliva have the same effect as cigarette smoke particles on the sensor.

 


7. How to use the breathalyzer to get an accurate result.

- Always use fresh batteries. Whenever possible, use a car adapter for the AL7000.

-Breath normally before blowing into the breathalyzer. Many people tend to take a deep breath prior to blowing into the breathalyzer. This will dilute the alcohol concentration.

- Breath in slowly through your nose, not your mouth.

- Inhale until about 70% and hold your breath for 2 seconds.

- Exhale gradually to make sure you have enough air to last for 5 seconds. Many people blow hard into the breathalyzer and run out of breath after 2 seconds, this leads to inaccuracy as most breathalyzers require a sampling time of 4 seconds.
