03 Generator used for Vair-9002 is designed for strong durability with no failure for a long time and the NO2 -NO Converter for measurement of NO2 is equipped with high efficient cartridge material which improves the change rate near 100%. All temperature adjustment system such as response cell, Converter, PMT, TEMP, etc are designed to be entered in the self software which is easy to use.

All gas analyzers of Vair series were equipped with screen interface design using TFT—LCD & Touch screen so that user can operate the analyzer and maximize the visual image, and MCU applied to the analyzer is 32bit ARM Cortex M4 processor and operates based on Linux Kernel 2.6 which maximizes the system 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, Analog out) so that users can use it more conveniently and usefully.
