PORTACAL® Carbonyl Sulfide (COS) Calibration Gas is designed for the calibration, bump testing, and verification of compatible carbonyl sulfide gas detectors, COS sensors, and monitoring instruments.

Carbonyl sulfide (COS) is a colorless, flammable gas with a distinctive sulfide odor. It is used in various industrial and agricultural applications, including as a fumigant, making reliable gas detection important in environments where carbonyl sulfide may be stored, handled, or present.

PORTACAL® Carbonyl Sulfide Calibration Gas provides a known concentration of carbonyl sulfide balanced in nitrogen to help verify that compatible COS sensors, portable gas detectors, fixed gas detection systems, and industrial gas monitoring instruments are functioning and responding properly.
