The standard rule is the more expensive the alcohol tester the more accurately it will measure, all our devices have a maximum deviation of 0.05% or less.
Depending on the type of sensor, it may or may not be able to register a new alcohol measurement faster, in short, with expensive devices you hardly need any time between different tests.
Depending on the brand and type, the devices have certain unique features, for example, some devices have a measurement history, calibration reminder, etc.
First ask yourself what you want to use the alcohol tester for, in other words how high-performance should the device be? How many mouthpieces will I need?
Compare the properties of the devices carefully with each other
If necessary, buy additional mouthpieces and a voucher for the next calibration after about a year
We take care of the rest and you enjoy your great device, your alcohol tester becomes your most loyal companion
