Electrochemical sensors commonly used in breath alcohol testing devices detect a concentration of alcohol in a sample of fluid. The sample of fluid is introduced into the electrochemical sensor and a current is generated by the oxidation of the alcohol within the fluid. The electrical output from the electrochemical sensor, plotted over time, forms an output curve, which may be used to estimate the concentration of alcohol in the fluid sample. The technology disclosed herein includes various methods for determining the quantity of an electrochemically convertible substance in a fluid sample using a breath alcohol content device, including detecting water saturation level of the fluid sample. The disclosed technology involves measuring electrochemical sensor outputs to quantify alcohol content of the fluid sample.

A breath alcohol tester calibration station provides a user-friendly system and method for calibrating a breath alcohol tester with a much lower error rate than current systems and methods for calibrating breath alcohol testers. The calibration station includes a data connection to the breath alcohol tester and a fluid connection between the breath alcohol tester and a calibration standard. The calibration station is used to execute calibration processes on the breath alcohol tester using the calibration standard.
