Calibration Gas
Sulfur Dioxide (SO₂) 20 ppm + O₂ 20.9% Calibration Gas – Nitrogen Balance
- SKU:
- FX34-125-020
Description
The Sulfur Dioxide (SO₂) 20 ppm + Oxygen (O₂) 20.9% Calibration Gas is a precision calibration gas mixture designed for accurate calibration, bump testing, and verification of compatible gas detection instruments requiring sulfur dioxide and oxygen.
This calibration gas mixture contains 20 ppm Sulfur Dioxide (SO₂) and 20.9% Oxygen (O₂), with Nitrogen (N₂) balance and is available in 34L, 60L, and 120L cylinders with a C-10 connection.
Each cylinder is manufactured in the USA and provides traceable documentation to support your gas detection calibration program. Cylinders include a QR code providing convenient access from a smartphone or other compatible device to the cylinder-specific Safety Data Sheet (SDS) and Certificate of Analysis (COA).
Calibration gas is NIST traceable and produced under quality systems meeting ISO 17034:2016 for Reference Material Production, ISO/IEC 17025:2017 for Chemical Testing, and ISO 9001:2015 Quality Management standards.

Common Uses: Calibration and bump testing of compatible portable and fixed gas detection instruments requiring 20 ppm sulfur dioxide and 20.9% oxygen calibration gas.
Always verify the required calibration gas concentrations and follow the gas detector manufacturer's calibration and bump-test procedures before use.
Hazardous Material Shipping
Calibration gas cylinders are regulated for transportation as hazardous materials and must be shipped in accordance with applicable carrier and hazardous-material regulations. Available shipping methods and charges may vary based on cylinder size, quantity, destination, and applicable HazMat requirements.
Lead Time
Please allow approximately 3 business days for order processing prior to shipment. Lead times may vary depending on availability and order quantity.
Non-Returnable Product
Calibration gas is non-returnable. Because calibration gas is a certified gas mixture with a limited shelf life, cylinders cannot be returned or exchanged after shipment.
Please verify the gas concentrations, balance gas, cylinder size, and connection before placing your order.
