Like any other analytical instrument, alcohol testers must be calibrated to ensure their accuracy. Calibration benefits the aging of the sensor and other critical components. Calibration is checking and adjusting the accuracy of an alcohol tester by comparing the displayed results with a known value. For example, a known 0.5 per mille BAC alcohol concentration is blown through an alcohol tester, the device is adjusted by software to ensure that the correct display of 0.5 per mille is displayed on the screen. It is important to calibrate alcohol testers periodically to maintain accuracy. This calibration is done with "dry gas".

How often to calibrate?
A Dräger alcohol tester must be calibrated every year.

What are we doing?
* We perform a functional test
* We test the device and calibrate it software for the entire test range
* We use the "dry-gas" method for this
* We will return your calibrated alcohol tester by post

How can I return my device for calibration?

* Buy a calibration coupon for your Dräger, after payment you will receive a digital invoice by email
* Send the device back to us together with a printout of the digital invoice
* Do not send mouthpieces, batteries, or packaging. Best in a bubbled wrapper
* Describe in detail any or all other possible problems
* Preferably send by registered mail

What happens if my tester is found to be defective and needs to be repaired?
If, after calibration, it appears that your device is defective, we will always contact you and tell you what the possible repair costs are. We will never start the repair without your express permission. If you agree to the repair, the device will be returned to you after payment of the repair costs has been made.

When purchasing a new device of equal value or higher, the calibration costs will be refunded.

Periodic calibration ensures accuracy

We recommend that you calibrate your alcohol testers every year for the best measurement results.
