Service Update – AS 3547:1997 Breathalysers
As industry standards advance, we are committed to keeping our customers accurate, compliant, and confident in their alcohol testing programs. Please be advised that from 30 June 2027, we will cease repairs and calibration services for handheld breathalysers operating under AS 3547:1997, including the HH3, HH4, and LE5 models.
To maintain compliance, organisations will need to transition to instruments aligned with AS 3547.1:2019.
