Product Description
High-Capacity 50 PPM Sulfur Dioxide Calibration Gas – 116L Cylinder
This certified 50 ppm sulfur dioxide (SO₂) calibration gas mixture in air balance is supplied in a 116L (4.0 cubic foot) refillable aluminum C-10 cylinder at 1000 PSI.
Built for routine calibration programs, this larger-volume cylinder supports consistent detector verification across multiple instruments and monitoring points.
The higher gas capacity reduces cylinder replacement frequency for facilities performing scheduled bump testing and calibration maintenance.
Typical Facility Uses

Reactive Gas Stability for Accurate Readings
Sulfur dioxide is chemically reactive and may adsorb onto regulators and tubing.
Using a purpose-prepared calibration mixture helps maintain repeatable electrochemical sensor response and prevents drift during verification procedures.
Custom Calibration Standards Available
Made-to-order mixture.
Alternate concentrations, balance gases, and multi-component blends available for application-specific monitoring and cross-sensitivity verification.
