Product Description
Portable Trace-Level 5 PPM Sulfur Dioxide Calibration Gas – 60L Cylinder
This certified 5 ppm sulfur dioxide (SO₂) calibration gas mixture in nitrogen balance is supplied in a 60L (2.1 cubic foot) refillable aluminum C-10 cylinder at 1000 PSI.
Designed for on-site verification, this cylinder supports calibration of sensitive electrochemical sensors used during exposure assessments and portable monitoring surveys.
The smaller cylinder volume improves mobility for field technicians while maintaining reliable trace-level calibration accuracy.

Accuracy at Low Concentrations
Reactive gases such as sulfur dioxide can produce delayed or suppressed readings at low ppm levels.
Using a certified trace concentration calibration mixture helps confirm detector response and prevent false safe measurements during field verification.
