If you have purchased a BACtrack breathalyzer and need to calibrate it, simply send a request to Sunnysoft's email. Calibration is important to maintain the accuracy and optimal performance of your device.

Calibration is recommended at least every 12 months or after a maximum of 500 measurements, depending on the frequency of use. If the tester shows inaccurate or inconsistent results, or if the test values are abnormally high or low, it is necessary to have it calibrated by a professional. Also, if the tester has not been used for several weeks, it is advisable to periodically "revive" the sensor by breathing into the device to prevent it from drying out.

Calibration takes place under controlled conditions, with technicians verifying the accuracy of the device and performing various diagnostic tests. After calibration, you will receive reports on the status of the device, which will be returned in a fully functional condition.

Remember that calibration is not covered by the device warranty, which only covers manufacturing defects. For details on calibration or if you have any further questions, please contact Sunnysoft via email.
