With this lightweight, inherently safe portable gas leak detector, users can quickly identify fugitive emissions of both organic and inorganic compounds for Method 21 compliance, LDAR applications, and site remediation.

The Thermo Scientific™ TVA2020 Toxic Vapor Analyzer can be set up as as an FID analyzer (flame ionization detector) or as a dual detection FID analyzer and PID analyzer (photo ionization detector). Reduced response times, improved user-serviceability, and Bluetooth™ connection are important characteristics.

Easy Operation
The TVA2020 Toxic Vapor Analyzer is smaller than the majority of standalone FID analyzers and 21 % lighter than previous models. As well as being easy to service in the field, the lightweight and compact design minimizes fatigue for true portability. A basic or improved probe, a carrying case, and a hydrogen refill assembly are among the other options.
Concentration data is transmitted via optional Bluetooth communication to a portable device that houses the LDAR software database. This eliminates the need to transfer files after monitoring and increases access to route information.
The Technology Users Expect
Detect gas leaks from refineries and chemical industries to ensure compliance with the US EPA Method 21 and LDAR programs. The TVA2020 Toxic Vapor Analyzer has an FID for measuring organic compounds with high sensitivity. The FID technique provides a large dynamic and linear range, resulting in steady and repeatable responses.
The analyzer supports both FID and PID technologies, allowing for simultaneous detection and better analytical capabilities. This dual setup can produce faster readings of organic and inorganic compounds than a single detector technology and offers more complete gas coverage than PID and FID analyzers of comparable size.
After conducting a primary calibration (the calibration kit is provided), the TVA2020 Analyzer can be configured by enabling internal logging settings, downloading a monitoring route, connecting via Bluetooth, setting alarm levels, and activating response factors.
