The Vair-9001 SO2 Analyzer is the analyzer that measures the minimum amount of SO2 in air correctly using the UV fluorescence method. The UV lamp with a lower chance of sensitivity used for Vair-9001 was applied, and the self-manufactured kicker to remove the obstacle components such as HC was installed.
To prevent the adhesion of the specimen, the response chamber and specimen tube of special coating material were used to improve minimum detection and precision.
All gas analyzers of the Vasthi series were equipped with a screen interface design using a TFT-LCD and touch screen so that the user can operate the analyzer and maximize the visual image. The MCU applied to the analyzer is an ARM11 32-bit processor and operates based on Linux Kernel 2.6, which maximizes the system's stability due to multiprocessing.
In addition, the analyzer is equipped with an automatic zero correction system (Auto Zero) for smooth measurement and various interfaces (Ethernet, RS232, RS485, USB, DIO, and Analog Out) so that users can use it more conveniently and effectively. US EPA Reference Method: RFSA-1120-257
