Intoximeters recommends that for all evidential grade breath alcohol analyzers, external accuracy checks and calibrations be performed using a NIST traceable dry gas or wet bath standard approved for use by both NHTSA and Intoximeters.

We are now offering all standard and custom NIST traceable gas concentrations in three NHTSA and Intoximeters approved volumes;  108 liter tanks, 55 liter tanks and 30 liter tanks.

For screening programs where NIST traceability is not required, Mini-Alco Cans are available for instrument accuracy checks and calibrations.
