Product Description
221L High-Capacity 3-Gas Calibration Gas for CO, CO₂ (1,000 PPM), and O₂ Detection
This 221L disposable calibration gas cylinder provides a consistent mixture of Carbon Monoxide (CO) 100 PPM, Carbon Dioxide (CO₂) 1,000 PPM, and Oxygen (O₂) 20.9% balanced in Nitrogen.
The 1,000 ppm CO₂ concentration is widely used for indoor air quality (IAQ) monitoring, HVAC ventilation validation, and environmental compliance testing, making this an ideal solution for large-scale or high-frequency calibration programs.
