Product Description
4-Gas Calibration Gas for Portable Gas Detector Accuracy
This calibration gas mixture contains Hydrogen Sulfide (H₂S) 20 ppm, Carbon Monoxide (CO) 60 ppm, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 15.0% balanced with Nitrogen.
The gas blend is supplied in a 34L disposable aluminum cylinder pressurized to 500 PSI with a C-10 valve, providing a stable and portable calibration solution for multi-gas detectors used in industrial safety monitoring.
Reliable Calibration for Multi-Gas Detection Instruments
Portable gas detectors must be calibrated regularly to maintain accurate sensor response. This quad-gas calibration mixture allows technicians to verify detector performance, perform bump testing, and maintain proper instrument sensitivity before entering hazardous environments.
Routine calibration helps ensure reliable monitoring of:
• Hydrogen sulfide exposure
• Carbon monoxide hazards
• Combustible gas levels (LEL)
• Oxygen deficiency or enrichment
Methane LEL Calibration for Combustible Gas Sensors
The methane concentration of 1.45% (58% LEL Pentane Equivalent) allows proper calibration of combustible gas sensors used in portable gas monitors. This concentration helps ensure accurate response to flammable gas conditions in confined spaces and industrial environments.
Portable Disposable Cylinder for Field Calibration
The 34L disposable aluminum cylinder is lightweight and convenient for technicians performing calibration or bump testing in the field. Disposable cylinders eliminate the need for gas returns or refilling while maintaining consistent gas concentration and stability.
Cylinder specifications include:
• 34 Liter cylinder capacity
• 500 PSI fill pressure
• C-10 valve connection
• Aluminum disposable cylinder
• Reactive gas mixture
Compatible with Most Portable Multi-Gas Detectors
This 4-gas calibration mixture is commonly used for calibration and bump testing of portable detectors monitoring:
• Hydrogen sulfide (H₂S)
• Carbon monoxide (CO)
• Combustible gases (LEL methane equivalent)
• Oxygen (O₂)
Always confirm calibration gas concentrations recommended by the gas detector manufacturer.
