Phosphine Detectors - PH3 Gas

Our selection of fixed or portable phosphine detectors available in single gas or multi gas versions are equipped with electrochemical sensors and used to monitor PH3 concentrations in the air. Phosphine gas, or phosphorus trihydride - CAS: 7803-51-2 - is used in international transport for fumigation activities due to its biocidal properties. It is also found in other industrial fields and in metal processing activities (anti-rust and impurities treatments). PH3 gas is dangerous to humans because it is extremely toxic and can cause chemical burns. It is also very explosive and can generate spontaneous combustion in the air. The explosive measurement scale will not be used for this extremely toxic gas. It will be necessary to be equipped with a PH3 detector in PPM or in PPB to monitor toxicity.
