The blend also includes hydrogen sulfide stabilization and precise ratios for oxygen and methane simulants. It is suitable for calibrating several MSA detector models (Altair 4, 4X, 4XR, 5, 5X, Sirius) and supports extended shelf life of up to 24 months from order date.
4-Gas Calibration Blend for BW Technologies
This 34-liter cylinder includes a high CO concentration of 100 PPM as part of a 4-gas mix for BW Technologies detectors. It also features hydrogen sulfide stabilization and a complete gas composition: 25 PPM H2S, 100 PPM CO, 50% LEL methane, and 18% oxygen, with balance nitrogen. The cylinder supports 24-month shelf life and is compatible with BW test and calibration systems.
Multi Calibration Gas: 50 PPM CO, 29L Cylinder
This Norlab by Norco multi-calibration gas blends 50 PPM CO with other gases in a 29-liter cylinder. It supports compatibility with multiple regulator families, including 500 Series Preset Flow, Trigger Control Series, 6000 Series Multiflow, and 8000 Series Demand Flow, enabling versatile calibration workflows and consolidated stock for safety programs.
Buying Guide
- Calibration gas concentration: Match the CO ppm specification to your detector’s calibration needs. Common values include 10, 50, and 100 PPM CO; some blends combine CO with H2S, CH4, and O2 for multi-gas detectors.
- Cylinder size and weight: Larger cylinders (e.g., 17 L or 58 L) provide longer service life but are heavier to handle. Plan for storage space and handling equipment.
- Shelf life and storage: Check manufacturer-specified shelf life and storage conditions. Gas stability and cylinder coating can affect accuracy over time.
- Regulator compatibility: Verify that the calibration gas integrates with your regulator models (Preset Flow, Multiflow, Demand Flow, etc.). Incompatibility can impede calibration throughput.
- Gas blend scope: For multi-gas detectors, consider 4-gas blends that include CO alongside H2S, O2, and LEL components to support comprehensive calibration across detector families.
- Certifications and calibration traceability: Where applicable, prefer products with standard references or NIST traceability to ensure confidence in performance.
- Storage and safety: Maintain cylinders upright, secured, and in a ventilated area. Follow all safety guidelines for compressed gas handling and regulatory compliance.
These options emphasize reliable CO calibration performance across common detector brands and regulator systems. When selecting a calibration gas, prioritize a match between cylinder content, regulator compatibility, shelf life, and the specific detectors you service to ensure consistent, objective calibration results.
