Abstract

A gas measurement system includes a first test unit for measuring the concentration of a selected gas at a first location, a second test unit for measuring the concentration of the selected gas at a second location, and a comparator for comparing the measured concentration of the selected gas from the first location with the measured concentration of the selected gas from the second location. An alarm indication is provided when a difference between the first and second measurements is greater than a user defined value or percentage. In an exemplary embodiment, the gas measurement system is configured to detect an ozone leak.
