Beware alcohol breath devices claiming to be Australian Standards AS3547 certified and workplace suitable when they are only certified for monthly calibration, not 6 monthly. Ask the supplier for a copy of the AS3547 Certificate. Do not be caught out with a device that must be calibrated every 30 days in order to obtain a AS3547 certified result.
Beware of alcohol breath testing devices claiming to be Australian Standards AS3547 certified, while only reading to 2 decimal places eg 0.05. These products may only be AS3547 certified for their “Pass/Fail” (qualitative) mode function, NOT their decimal place function. This renders these devices unsuitable for the workplace as any 2 decimal place reading will not be considered an AS3547 certified result.
