Product details
TVA2020CToxic volatile gas analyzer
Lightweight and intrinsically safe portable FID/PID dual detector analyzer
The Thermo Scientific TVA2020C toxic volatile gas analyzer is the only portable on-site analyzer that utilizes both flame ionization (FID) and photoionization (PID) dual detector technologies, ensuring intrinsic safety.
FID/PID dual detector technology;
Equipped with Bluetooth function
Lightweight and compact design
Easy on-site operation
No need for PC application software
The Thermo Scientific TVA2020C toxic volatile gas analyzer has the ability to simultaneously detect organic and inorganic compounds. The TVA2020C analyzer can be applied to on-site monitoring, on-site remediation testing, landfill environmental monitoring, and routine regional environmental investigations that comply with US EPA Method 21.
TVA2020C is equipped with a highly sensitive flame ionization detector (FID) to measure the concentration of organic compounds. FID has a wide dynamic and linear measurement range, stable response, and good repeatability. The analyzer equipped with FID and PID dual detectors that can work simultaneously has stronger analytical capabilities. Compared to single detector instruments, dual detector analyzers can quickly respond to all organic compounds and some inorganic compounds simultaneously; Compared to other instruments of the same volume, it can provide more comprehensive gas coverage.
After calibration, TVA2020C can perform some custom settings, such as setting internal data recording parameters, uploading monitoring paths, establishing Bluetooth connections, setting alarm levels, selecting response factors, etc.
The optional Bluetooth communication function can directly send a large amount of measurement data to handheld devices with built-in LDAR software, so there is no need to transmit it to the monitoring system after measurement, and it can better monitor based on path information.
The TVA2020C reduces weight by 21% compared to earlier models and is more compact in size than most single FID instruments. This lightweight and compact portable design can truly reduce user fatigue. In addition, some configurations of TVA2020C are optional, such as basic/enhanced probes, portable cases, and hydrogen inflation valves.
Technical parameters of TVA2020C toxic volatile gas analyzer
| Accuracy |
FID ranges from 1.0 to 10000ppm, with a reading of ± 10% or ± 0.1ppm, taking the maximum value PID ranging from 0.5 to 500ppm, with a reading of ± 20% or ± 0.5ppm, take the maximum value |
| Repeatability |
When FID is 500ppm methane, 2% When PID 100ppm isobutene, 1% |
| linear range |
FID 1.0~30000ppm methane PID 0.5-2000ppm isobutene |
| response time |
500 ppm isobutene is introduced into PID, and the time to reach 90% of the final value is less than 3.5 seconds FID introduces 10000ppm methane and takes less than 3.5s to reach 90% of the final value |
| Sampling traffic | At the entrance of the sampling probe, it is generally 1L/min |
| battery | At 0 ℃, it can work continuously for at least 10 hours; The full charge time of the battery is less than 10 hours; |
