Process gas analyser

About Process gas analyser

The 204A Process Gas Analyzer is a high-performance instrument designed for continuous and accurate analysis of process gases in industrial applications. Engineered for flexibility and precision, it enables simultaneous measurement of multiple gas components including CO, CO, CH, O, H, and N, making it ideal for gasification, syngas, and various process control environments.

Utilizing advanced sensing technologies such as NDIR (Non-Dispersive Infrared) for CO, CO, and CH, Thermal Conductivity Detector (TCD) for hydrogen, and electrochemical or optional paramagnetic sensors for oxygen, the analyzer ensures reliable, stable, and interference-free measurements. Its integrated sampling system with moisture and dust removal, along with an inbuilt suction pump, ensures accurate analysis even in challenging industrial conditions.

The 204A Process Gas Analyzer supports real-time monitoring, helping industries optimize process efficiency, improve safety, and maintain product quality. With features like automatic calibration, data logging, USB communication, and optional outputs such as 420 mA and RS485/Modbus, it offers seamless integration with PLC, DCS, and SCADA systems. This makes it a dependable and cost-effective solution for a wide range of industrial process monitoring applications.
