Product Description
221L 4-Gas Calibration Gas for CO, Low-Level CO₂ (1,000 PPM), CH₄ (LEL), and O₂ Detection
This 221L calibration gas cylinder is designed for calibration of detectors measuring Carbon Monoxide (CO) 50 PPM, Carbon Dioxide (CO₂) 1,000 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 20.9% balanced in Nitrogen. The 1,000 ppm CO₂ concentration is ideal for precision indoor air quality (IAQ) calibration, HVAC validation, and compliance-driven monitoring programs.
