  • Measures total volatile organic compounds
    • FID dynamic range 0 to 50,000 ppm
    • (optional) PID dynamic range 0 to 2,000 ppm
  • Built-in sampling pump 1000 cc/min flow rate (nominal).
  • Hydrogen cylinder provides over 8 hours of continuous operation.
  • Rechargeable battery provides at least 8 hours of operating time.

NOTICE: If you require the hydrogen tanks to be shipped filled with hydrogen, it is considered a hazardous shipment and will incur extra shipping fees.  We include the hydrogen tank fill adaptor if you prefer to find your own source of ultra-high purity hydrogen to fill the tanks with.

The Thermo Toxic Vapor Analyzer (previously known as the Foxboro TVA 1000) is an intrinsically safe organic vapor analyzer (OVA) used to measure volatile organic compounds (VOCs). The TVA 1000 is a portable flame ionization detector (FID), making it easy to carry around for gas leak detection of methane and other applications (hazardous waste sites, emergency response, industrial hygiene, natural gas leak detection, underground storage tanks, fugitive emissions monitoring, and EPA method 21 monitoring). One benefit to using a FID rather than a photoionization detector (PID) is that an FID can be used as a methane gas detector (PIDs do not detect methane).

The Thermo TVA 1000 is one of the few OVAs that have a model with dual PID/FID measurement capability. Enviro-Equipment, Inc. offers rentals on both the FID only model and the PID/FID combination model. We ship two hydrogen clyinders filled with hydrogen unless the customer has their own source of ultra high purity hydrogen. Additional hydrogen cylinders are available for rental. Charcoal filter adapters are available for applications where VOCs other than methane need to be filtered from the readings.
