Product information
product name: Phosphine PH3 gas detector
product brand: Skyeaglee
Product number: SK-600-PH3
Measurement object: Phosphine in the air
product description
体简介: Gas introduction:
Phosphine is a colorless, highly toxic and flammable liquefied compressed gas stored in steel cylinders. Its storage pressure is its vapor pressure of 522 psig. This gas is heavier than air and has a smell similar to that of stinky fish. Spontaneous combustion can occur if trace amounts of other phosphorus hydrides such as ethyl phosphine are encountered. Phosphine should be treated as a highly toxic and spontaneous combustion gas. The relative density is 1.17. Melting point -133 ° C. The boiling point is -87.7 ° C. Spontaneous ignition point is 100 ~ 150 ℃. The vapor pressure is 20atm (-3 ° C). The lower explosive limit of mixture with air is 1.79% (26g / m3). Slightly soluble in water (20 ° C, can dissolve 0.26 volume of phosphine). Trace amounts of P2H4 in the air can spontaneously ignite; explosion can occur when the concentration reaches a certain level. Phosphides are formed by burning metal blocks, and hydrogen is evolved. It can also react with copper, silver, gold and their salts.
