All alcohol breath testers require calibration at recommended, regular intervals to ensure accuracy. Calibration is the process of checking and adjusting the internal settings of a breathalyzer by comparing and adjusting its test results to a known alcohol standard. Without exception, all professional users of alcohol testers, including Law Enforcement personnel and Corrections personnel, have rigorous policy and procedures in place to calibrate, verify and document their breath testing equipment.
There are two methods of calibrating a precision fuel cell breathalyzer, the Wet Bath and the Dry Gas method. Each method requires specialized equipment and factory trained technicians capable of calibrating a breath alcohol tester to the highest standards. It is not a procedure that can be conducted by untrained users or without the proper equipment.
Our breathalyzers come calibrated from the factory.
It is important to keep your personal breathalyzer calibrated to maintain the accuracy of the unit. Consult your owners manual for recommended calibration frequency on your device.
The cost of a calibration service is $25.00 per calibration. Included with calibration, your LifeGuard is also run through a series of diagnostic and performance tests to ensure it is in peak operating condition. Details are included in the LifeGuard Operating Manual included with your purchase.
1. Print and complete the Calibration Order Form or enter the required information through the on-line shopping cart.
2. Ship the unit (postage prepaid) to the following address:

To ensure delivery and tracking of your unit, we recommend that you request a delivery confirmation with your shipment.
3. Enclose payment along with the calibration order form (payable to Lifeloc Technologies, Inc.) and the unit to be recalibrated. Include your return shipping address.
4. Upon receipt at the factory, your LifeGuard will be recalibrated, tested and shipped back to within 10 business days.
5. For your records, you will receive a "certificate of calibration" with your unit.
Q. What happens to my unit if I don’t get it calibrated every 12 months?
A. As with any alcohol testing device, if the LifeGuard is out of calibration it may not provide accurate breath alcohol content readings. The BAC reading may be either higher or lower and you will not know which.
Q. How do I know when my LifeGuard requires calibration?
A. We recommend you have the unit recalibrated once every 12 months.
Q. Can I recalibrate the LifeGuard myself?
A. No. You need the use of advanced breath alcohol simulators and factory trained technicians to correctly perform a calibration.
Q. Do you recalibrate other personal breath alcohol testers besides LifeGuard?
Q. My older semiconductor based breathalyzer needs calibration much more frequently than you do for LifeGuard, especially under heavy use. Why?
A. LifeGuard is a precision fuel cell breath tester. Unlike inexpensive semiconductor based breathalyzers which are prone to fail after heavy use or after infrequent use, the LifeGuard is engineered around a proven and reliable technology – the Lifeloc Platinum Fuel Cell
Q. If I did not purchase LifeGuard directly from your website, can I have you recalibrate my device?
A. Yes. Simply follow the procedures described above.
Q. Is calibration included in the one-year warranty?
A. No. The warranty is limited to any defects with the unit, and does not include routine maintenance such as calibration.
