The AlcoblowPro® ALC-303 is an upgraded version of the ALC-308, featuring a relay function that controls vehicle ignition. If alcohol is detected, the tester prevents the engine from starting, ensuring that only sober drivers can operate the vehicle.
This model retains all the features of the ALC-308, including the fuel cell sensor, 4G communication for big data management, and wide voltage (DC5-24V) compatibility, but adds an engine start control function for enhanced safety in fleet operations.
