The TVA1000B is the only portable, intrinsically safe, survey flame ionization (FID) and photoionization (PID) dual monitor which provides fast and accurate readings of organic and inorganic vapors and meets EPA Method 21 specifications for monitoring fugitive emissions.TVA1000B is built for fast, simple operation in real-world field conditions. A large keypad ensures straight-forward, easy operation, with or without gloves. Datalogging is activated by a thumb-switch on the hand held probe. Operations are menu-driven and displays are bright and easy to read.The TVA-1000B is the only over-the-shoulder portable vapor analyzer that offers both PID (Photo Ionization Detection) and FID (Flame Ionization Detection) in a single, easy-to-use instrument. You can easily carry the TVA-1000B to any plant or field location, thanks to its compact size. With the TVA-1000B, you can rapidly monitor and log inorganic and organic vapors simultaneously, on-line, with ease.
FID Detection allows users to measure a wide variety of organic vapors over an impressive dynamic range (0-50,000 ppm). FID allows the user to monitor some compounds that the PID will not detect. The flame ionization detector operates by breaking Hydrogen-Carbon bonds and is not limited by the ionization potential of the molecule.

The TVA 1000B with both Photo Ionization Detection and Flame Ionization Detection operating simultaneously in a single portable vapor analyzer. Dual detection eliminates the time, expense and trouble of purchasing and maintaining two separate analyzers. With a dual detector, the user has not only the ability to monitor for organic compounds, but also can detect inorganic compounds with the use of the PID. Some compounds detected by PID and not FID are ammonia, carbon disulfide, carbon tetrachloride, formaldehyde, and hydrogen sulfide. The PID also has the advantage of not requiring fuel or air to operate.
