Based on non-dispersive infrared sensor, CO2 and CH4 Meter measures up to 100% methane and 50% carbon dioxide levels in real-time, or can be used as data logger to record gas levels over time. Meter is available as hand-held, battery-operated device, or in permanently mounted NEMA4 enclosure. Both use built-in micro-pump to take sample via tube port, measure sample, and return it via second tube port to form closed-loop gas measurement system.
