Product Description
50 PPM Sulfur Dioxide Calibration Gas – 44L Reactive Gas Standard
This certified 50 ppm sulfur dioxide (SO₂) calibration gas mixture in air balance is supplied in a 44 liter (1.5 cubic foot) C-10 aluminum cylinder at 750 PSI.
Designed for stability in low-concentration reactive gas applications, this mixture supports accurate span calibration and functional testing of fixed and portable gas detection instruments.
SO₂ is a chemically reactive gas that can adsorb onto regulator surfaces and tubing. Using a purpose-built calibration mixture helps maintain sensor response accuracy during verification and maintenance intervals.
