The Thermo Scientific Toxic Vapor Analyzer, model TVA1000B, 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. The ability to utilize both technologies in this field proven instrument provides benefits in reduced weight and a single user interface. The user can easily monitor and log inorganic and organic vapors simultaneously.
Analyzer monitors and logs organic and inorganic vapors simultaneously; suitable for use in a broad range of applications including fugitive emissions monitoring, emergency response, hazardous waste site evaluation, industrial hygiene, underground storage tank investigations, and natural gas leak detection.

Fugitive Emissions Monitoring
- The unique dual detector FID/PID design can handle a wide range of compound vapors present at processing plants. The TVA1000B permits monitoring at lower ppm levels.
Emergency Response
- For reliable measurements of hazardous spills or emissions, the TVA1000B responds quickly in an emergency. The ability to quickly detect the presence of “hot spots” is key to locating the source of the hazard.
Hazardous Waste Site Evaluation
- The TVA1000B allows quick and easy identification of the hazard location and quantifies the level of contamination.
Underground Storage Tanks
- The TVA1000B is a primary tool for determining if a UST is leaking and the extent of the contamination.
Industrial Hygiene
- The TVA1000B can help you maximize the effectiveness of your plant ventilation system, and identifies trouble spots. Use it to survey ambient vapor levels in specific breathing zones or in general plant environments, and log for furthur follow-up action.
Natural Gas Leak Detection
- The TVA1000B enables quick and easy detection of natural gas leaks.
