AlcoSense Blow Tubes 20s
AlcoSense Blow Tubes are nessesary for the AlcoSense Lite, Elite, SE and Zero, but also fit the AlcoSense Excel, Pro and Ultra (for ultimate accuracy we recommend using the AlcoSense Professional Mouthpieces with the Excel, Pro and Ultra).
The blow tubes have a rough interior surface which helps to reduce condensation build up in the breathalyzer and improve reading accuracy. Always use a blow tube with your breathalyser, it greatly reduces the risk of saliva ingress into the blow chamber and improves the lifetime of your breathalyzer.
