Witt-Gasetechnik (www.wittgas.com) introduced a portable, compact and lightweight gas analyzer to monitor and measure gas mixture to the torch. PA-O₂/CO₂ measures the O₂ and CO₂ concentration at the point of use. The analyzer is designed to make measurements periodically or continuously. An alarm is activated if the gas contents exceed set limits. The last 100 measurements can be recorded for quality control documentation by using Witt's logger software.
