For hassle-free calibrations, sign up for a calibration management plan instead. It will not only save you time, it is also cheaper and faster than booking in a calibration manually each time.

With a calibration management plan, all that happens after sign up is:

  1. We email you the e-parcel label, you print it out and send your breathalyser or sensor back to us.
  2. We calibrate your breathalyser or sensor, and send it back to you.
  3. Some of our plans come with additional mouth pieces, batteries, shipping insurance etc.
