PORTACAL® Phosphine (PH₃) Calibration Gas is designed for the calibration, bump testing, and verification of compatible phosphine gas detectors, PH₃ sensors, and monitoring instruments.

Phosphine (PH₃) is a colorless, highly toxic, and flammable gas used and encountered in a variety of agricultural and industrial applications. It is commonly associated with grain and stored-product fumigation, agriculture, pest control, semiconductor manufacturing, chemical processing, and other environments where accurate phosphine monitoring may be required.

PORTACAL® Phosphine Calibration Gas provides a known concentration of phosphine to help verify that compatible PH₃ sensors, portable gas detectors, fixed gas detection systems, and industrial gas monitoring instruments are functioning and responding properly.
