Product introduction:
The TVA2020C toxic volatile gas analyzer is the only portable on-site analyzer with the technology of flame ionization (FID) and photo ionization (PID) double detector simultaneously.
Detailed description of the product
FID/PID dual detector technology;
Light and compact design;
The operation of the field is simple;
There is no need for PC application software.
PDA hand operator
The Thermo Scientific TVA2020C toxic volatile gas analyzer has the ability to detect both organic and inorganic compounds at the same time. The TVA2020C analyzer can be applied to field repair detection, landfill site monitoring, and regular regional environmental survey, which is followed by the 21 EPA monitoring method.
TVA2020C is equipped with a highly sensitive flame ionization detector (FID) to measure the concentration of organic compounds. FID has a wide range of dynamic and linear measurement, stable response and good repeatability. The analyzer with both FID and PID dual detectors, which can work at the same time, has a stronger analytical ability. Compared with the instrument of single detector, dual detector analyzer can respond to all organic compounds and other inorganic compounds at the same time. Compared with the same volume of other instruments, it can provide more comprehensive gas coverage.
After correcting, TVA2020C can do some custom settings, such as setting up internal data recording parameters, uploading monitoring paths, building Bluetooth connections, setting alarm levels, selecting response factors, etc.
The optional Bluetooth communication function can send a lot of measurement data directly to the handheld device of the built-in LDAR software, so it doesn't need to be transmitted to the monitoring system after measurement, and it can also monitor the path information better.
TVA2020C reduces the weight of the earlier model by 21%, and is more compact than most single FID instruments. This portable, compact, portable design can really reduce the fatigue of the user. In addition, some of the TVA2020C configurations are optional, such as the basic / enhanced probe, the PDA hand operator, the portable box and the hydrogen gas valve.
Product parameters:
PID instrument - - reading + 20% or + 0.5ppm, large value, from 0.5ppm to 2000ppm. This accuracy is calibrated with isobutene at 100~300ppm (including drifting) on time temperature and humidity at school.
FID instrument - - reading + 10% or + 1.0ppm, large value, from 1.0ppm to 10000ppm. This accuracy is used for single point calibration of methane at 100~500ppm (including drifting) on time temperature and humidity at school. In the range of 3000 to 30000ppm, the calibration error of the calibration readings is + 10% with 15000ppm methane.

Data storage interval
Auto Mode automatic mode - - 1 / sec to 1 /999, VOC or FE (user selectable volatile leakage) Mode mode - - - 2 to 30 seconds, the user selectable. The sampling rate is at the entrance of the sampling probe, and the rating is 1LPM..
Battery
When the battery is filled with electricity for up to 10 hours and at 20 degrees Celsius (32 degrees Fahrenheit), the working time is at least 10 hours. The use of background light on the probe will shorten the battery life. The battery can be replaced by opening the back of the instrument.
Warning: do not replace batteries in any dangerous area due to the presence of flammable gases
Battery charger
Battery charger is an independent unit that can recharge the battery inside the instrument while the instrument is working. The charger is full of electricity in the battery for up to 14 hours. If the instrument is charged when working, the charging time will be longer. Two types of charger are available, one is 90VAC alternating current, 50/60HZ or 230VAC AC, 50/60HZ.
