摘 要：The Thermo Scientific Toxic Vapor Analyzer (TVA)-1000B is an intrinsically safe direct reading portable monitor that uses either a flame ionization detector, a photoionization detector, or both simultaneously to provide real-time measurements of organic and some inorganic vapor concentrations in air. This field guide provides operators and incident commanders the basic concepts for effective use of the TVA-1000B, including principles of operation and supplies required.
