Product Description
High-Capacity 5 PPM Sulfur Dioxide Calibration Gas – 120L Cylinder
This certified 5 ppm sulfur dioxide (SO₂) calibration gas mixture in nitrogen balance is supplied in a 120L refillable aluminum C-10 cylinder.
Designed for routine verification of sensitive electrochemical sensors, this larger cylinder supports ongoing exposure monitoring and documented compliance programs.
The higher gas volume reduces cylinder replacement frequency in facilities performing repeated verification checks.
Typical Applications
-
Continuous industrial hygiene monitoring
-
Exposure documentation programs
-
Environmental monitoring systems
-
Laboratory verification schedules
-
Multi-instrument maintenance programs
-
Safety compliance recordkeeping
Reliable Trace-Level Accuracy
Reactive gases such as sulfur dioxide may adsorb to surfaces and affect low-ppm measurements.
Using a certified trace-concentration calibration mixture helps maintain repeatable detector response and prevents inaccurate safe readings.
