In short: We calibrate Alcovisor and most other breathalyzers. Price €25–€45 incl. VAT depending on the model, turnaround 3 working days Bring it in or send it from anywhere in Lithuania.
Calibration is not a button press. It is a controlled comparison with a reference under the conditions of human breath.
1Reference solution
An ethanol solution of known concentration is used.
234 °C simulator
The simulator warms the solution to breath temperature and holds it – temperature affects accuracy most.
3Two reference points
We adjust at 0.5 and 1.0‰ (stationary units also at 1.5‰), so the whole common range is accurate.
4Check after adjustment
After adjustment, readings are checked against the reference again.
Why calibration matters
Explanatory simulation – not real measurement data.
Reference
Tolerance
An ageing sensor reads low
When to calibrate right away
More than 6 months since the last calibration
Readings look unusual or differ a lot between tests
The device was dropped, got wet or was unused for long
The breathalyzer itself shows a calibration reminder
Metrological verification is coming up
This recommendation follows manufacturer guidance; calibration frequency is not in itself a legal requirement.
