Product code:



The AlcoLimit Protector Vehicle Interlock is an ideal solution to keep your fleet vehicles and forklifts safe from employees driving under the influence. Employees simply blow into the Protector breathalyser handset and if there is no alcohol present the ignition can be started. Available in both 12v and 24v options.

The AlcoLimit Protector Vehicle Interlock is also very popular with people coming off of a court ordered interlock device. The Protector Interlock provides the same level of protection against drink driving to ensure a second offence does not occur. As anyone who has been caught DUI will know, it is very costly getting caught the first time but the second time you get caught the penalties imposed are much heavier.


A simple module is connected to the ignition (any auto electrician can install it) which is either activated or deactivated by the result provided by the AlcoLimit Protector Interlock breathalyser handset.The breathalyser handset can also be used independently as a portable breath alcohol tester allowing you to test yourself at the pub prior to going out to your vehicle.


Recommended for use in all workplaces, transport, construction, mining, airports, engineering & manufacturing. Ideal for screening all employees in safety sensitive fields or sales representatives out on the roads.

3 decimal point accuracy with a range of 0.000%BAC to 0.400%BAC.


Conforming to Australian Standards AS3547 ensures the accuracy, durability and functionality of the Protector breathalyser has been thoroughly tested.



In-built Safety and Precision Technologies


AlcoLimit's Flow Control Technology means that the sensor checks the flow rate of your breath and must receive an adequate air sample before it will provide you with a reading. This is just one of the safety measures built into the AlcoLimit range.


AlcoLimit's Intelli-sensor Recognition Technology checks the sensor condition every time you use your breathalyser. Stability of the sensor is analysed as well as the level of alcohol residue built-up on the sensor. An indication will be given if the sensor needs recalibration.

In-House Calibration

Our in-house technicians will specifically calibrate your breathalyser in accordance with Australian Standards regulations for the Australian/New Zealand legal limits.

Regular calibration is required to maintain the specified accuracy of each device. An in-built usage counter and an on-screen recalibration reminder make remembering to have your unit serviced simple.

Our flat-fee servicing cost includes return overnight freight. Turnaround is guaranteed 3-4 working days.


see Recalibration/Servicing page for further details.


Please Note: for accurate results users must wait at least 20 minutes after the cessation of drinking before testing. Use prior to this time will result in inaccurate readings and shorten the lifespan of the sensor.
