We recommend calibration around every 12 months.
Calibration services are included with your BACtrack View Enterprise subscription at no extra cost. Simply send an email to support@bactrack.com when you are ready to get your breathalyzer calibrated, and we will send a replacement within 3-5 business days.
NOTE: You are required to mail the original unit back using the shipping label we provide in your email. This service is for active BACtrack View Enterprise members only.
