Product Description
221L Oxygen (O₂) 19.5% Calibration Gas for Oxygen Deficiency Alarm Testing and Sensor Verification
This custom calibration gas mixture contains Oxygen (O₂) 19.5% balanced in Nitrogen, supplied in a 221L steel cylinder at 250 PSI with a CGA-165 valve.
Designed for calibration, bump testing, and routine verification of oxygen monitoring instruments and gas detection systems, this mixture provides a reliable oxygen concentration for validating sensor response and maintaining detector accuracy. The blend is commonly used in industrial safety programs, confined space monitoring applications, environmental monitoring, manufacturing facilities, laboratories, and compliance-driven safety programs.
The 19.5% oxygen concentration corresponds to the OSHA-defined threshold for oxygen-deficient atmospheres, making this mixture particularly valuable for oxygen-deficiency alarm testing, confined space safety programs, detector verification, and preventive maintenance procedures. Safety professionals commonly use this blend to verify alarm setpoints and ensure oxygen monitoring equipment responds properly to potentially hazardous atmospheric conditions.
The larger 221L cylinder supports calibration programs involving multiple instruments while reducing cylinder replacement frequency and minimizing downtime during scheduled maintenance and compliance testing activities.
