Draeger INTERLOCK® XT
The Draeger INTERLOCK® XT is a breath alcohol measuring instrument that can prevent a vehicle from being started if the driver's breath alcohol concentration is higher than the state's limit.
Product benefits
- First blow, then turns on the ignition
- Prior to starting the engine, the Draeger Interlock® XT requests a breath sample. If the driver is alcoholized, the immobilizer system inhibits the motor from starting. Otherwise, the starter is activated for the driver to start the vehicle. The device will also prompt the driver to retest periodically while en route. The device will not disrupt the engine function once the engine has been started, however the event will be recorded. Some states require the horn to sound and / or the headlamps to flash if a retest is failed.
- High measurement accuracy
- The Draeger Interlock® XT determines the breath alcohol concentration via an electro-chemical sensor system as it is used in respective police measuring devices. The device is responsive to alcohol only.
- Fast usability
- To avoid long waiting periods, Draeger put emphasis on the Interlock® XT always being fast ready to use quickly. Its functionality is as good at -40 °F as at +185 °F under direct sunlight. The name affix "XT" stands for "eXtended Temperature".
- Safe from manipulation
- The device immediately detects any attempt to use auxiliaries as air pumps or filters to bypass the Draeger Interlock® XT. In such case, it will inhibit the motor from starting.
- All events recorded in a data memory
- The data memory records more than 30.000 events and can be read via a special PC software.

Reliable preservation of evidence: Via the Dräger DCD5000, approximately 0.4 ml of oral fluid sample can be sampled, preserved and transported. The sampler shows a minimum volume variance. Thanks to reproducible recovery rates, semi quantitative conclusions can be drawn, concerning the concentration of the substance classes to be analyzed which were present in the sample at the moment of sampling.
