Product Description
221L High-Capacity 3-Gas Calibration Gas for CO (35 PPM), CO₂ (1,000 PPM), and O₂ Detection
This 221L disposable calibration gas cylinder delivers a precise mixture of Carbon Monoxide (CO) 35 PPM, Carbon Dioxide (CO₂) 1,000 PPM, and Oxygen (O₂) 20.9% balanced in Nitrogen.
The 35 PPM CO concentration supports low-level detection calibration and compliance-driven environments, while the 221L capacity enables extended calibration workflows across multiple instruments and locations.
