Our latest Breathalyzers include a unique and patented technqology that eliminates the need for routine re calibration. 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.
- The sensor is replaceable by users in a minute or less
- Eliminates the need for routine factory calibration
- Maintain your device readiness- crucial in Maritime application
- Always have a factory accurate breathalyzer
- Avoid recalibration of the old and often contaminated sensor
