Breathalyzers are a type of alcohol tester. A Breathalyzer can be purchased for for commercial, legal or personal purposes. There are two different types of alcohol breathalyzers: those that use a semiconductor sensor and those that use a fuel cell sensor.
Some important factors to be considered when purchasing a breathalyzer are:
• Does it meet required Australian Standards?
• Can it be recalibrated? Over time all alcohol breathalyzer sensors become less accurate and must be re-calibrated.
• Has the breathalyzer got a good accuracy, +/- 10%, as per AS3547?
