The Problem With Digital Breathalyzer Calibration Prism™ Technology Do you own a digital breathalyzer? Have you ever had the device calibrated for accuracy?With the exception of the AlcoMate Prism™ Technology, every fuel-cell breathalyzer in the world must be periodically re-calibrated by the manufacturer in order to maintain maximum accurate readings. It is inherent to alcohol sensing technology, much like gasoline engines in cars require oil changes in order to function properly. Most breathalyzers have to be physically mailed to a service center along with a fee to get this re-calibration done, and you will be without your device for weeks. Even after calibration, the service does not restore any wear on the alcohol sensor, and eventually your breathalyzer will fail completely due to the sensor breaking down.PRISM Technology was developed to improve the way breathalyzers are maintained for function and accuracy. Once the sensor becomes degraded resulting in a loss of accuracy, you can literally remove and discard the existing module containing the sensor and replace it with a newly manufactured, pre-calibrated replacement. The self-service is quick and easy, and the only way to restore true “Day 1” accuracy to your device.Sensor modules must be replaced every 200 tests or at least once yearly, whichever comes first. Modules should also be replaced if damaged or expired.Digital Breathalyzer Calibration and AccuracyThe AlcoMate® Premium breathalyzer combines professional reliability with extremely easy-to-use one-button operation. You can count on the Premium breathalyzer to serve all your personal and/or professional alcohol breath testing needs, as it is DOT approved for law-enforcement grade accuracy and US Coast Guard Approved to satisfy the requirements of all marine vessels in US waters to have a breathalyzer-on-board.AlcoMate is the only brand in the world that you can replace the sensor and requires NO calibration (US Patent No. 7,841,224 B2, also worldwide).Suggested UseWait 15 – 20 minutes after consuming alcohol before using any type of breathalyzer. It is recommended to drink water prior to taking the test as a way to remove alcohol or any other products in the mouth. Shop Now With PRISM™ Technology, Day 1 accuracy is restored with every new sensor. The sensor is the engine that make the breathalyzer work and makes it accurate. Changing the sensor is just as easy as changing a battery.
