Gas analyzers

SIRA CH₄ Low

Continuous measurement of trace amounts of methane in exhaust gases

The SIRA CH₄ low is a stationary indoor analyzer for real-time measurement of methane in low ppm concentrations in exhaust gas streams. The methane concentration is precisely determined using an infrared Harriot cell.

Due to the new EU methane regulation, the monitoring of methane in exhaust gases is becoming increasingly important. With the SIRA CH₄ low, methane levels in a wide variety of exhaust gases can be detected quickly, reliably and with high precision – a decisive contribution to compliance with regulatory requirements and process optimization.

Thanks to its customizable measuring frequency, extensive configuration options and virtually maintenance-free design, the SIRA CH₄ low offers an exceptional combination of flexibility, process safety and long-term reliability.
