We offer alcohol breathalyzers for both personal and professional use. We feature AlcoMate Breathalyzers that include a unique and patented technology that eliminates the need for routine breathalyzer calibration services. This technology allows users to swap their defective sensor themselves without the need for sending the device to ASD for re-calibration. The calibration parameters are stored in a nonvolatile memory residing on the sensor module itself that makes the device independent of its sensor contamination.
Replace the sensor module yourself and turn your device into its new condition. Think twice if you have decided to purchase a breathalyzer that lacks this technology.
