A three-in-one biogas-measurement device

By Chemical Engineering | March 1, 2019

Vaisala

The MGP261 (photo) is said to be the world’s first multigas measurement instrument for in-situ monitoring of methane, carbon dioxide and humidity, offering realtime gas composition data without sample extraction or treatment. This compact measurement instrument is Ex certified up to Zone 0, which enables inline installation in explosive atmospheres. The MGP261 gives continuous readings of methane, carbon dioxide and water vapor directly in process pipelines. It is optimized for biogas production processes, such as anaerobic digestion of waste from agriculture, industries and municipalities, as well as the utilization of landfill gas. The MGP261 is based on this company’s patented Carbocap technology for infrared gas measurement. — Vaisala Oyj, Helsinki, Finland
