FAQ: Mark X

Q: Do breathalysers require recalibration?

A: Yes they do — the Mark X Calibration intervals, Standard test mode – once a year or 1000 positive tests (whichever comes first), Screening mode – once a year or 3500 positive tests (whichever comes first) 👍 That’s why it’s never been more important to choose a supplier with excellent after-sales service.
