Portable Gas Analyzers for Optical Analysis
Instrava portable gas analyzers are designed for high-precision monitoring of multiple gases in industrial environments. Based on advanced NDIR (Non-Dispersive Infrared) detection technology, the analyzer provides reliable measurement of gases such as carbon monoxide (CO), carbon dioxide (CO₂), methane (CH₄), ammonia (NH₃), sulfur dioxide (SO₂), sulfur hexafluoride (SF₆), and hydrocarbons.
The instrument features an intelligent control system with a full English operation interface, making it easy for operators to perform gas analysis in field environments. Built-in temperature compensation and gas flow stabilization systems ensure accurate measurements even when environmental conditions change.
Designed for portable industrial applications, the analyzer supports fast response gas detection, automatic alarm functions, and long-term continuous operation, making it ideal for engineers and technicians who require reliable real-time gas analysis in various industrial processes.
