This is a personal breathalyzer which uses a new patented method of detecting alcohol in breath. It’s called PRISM which stands for Pre-calibrated Replaceable Intelligent Sensor Module. This is the height of innovation in alcohol testing. All units become less accurate with time due to residue buildup and functional degradation. The home breathalyzer does not require re-calibration so you don’t need to send the unit off regularly for checking. Instead, you replace the old sensor module yourself and the device is accurate right from the start.
These tests are approved by all major US enforcement agencies and are guaranteed accurate. The 4-digit results are displayed clearly on an easy to read LCD screen. The single-button operation makes it easy to use and the unit comes with a one-year warranty.
