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. A Certificate of Analysis for your Dry Gas Standard is available using our True-Trace application

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 34 liter tanks.
