Ambient Ozone Gas Analyzer

The O₃ Vair-9004 analyzer accurately measures the minimum amount of O₃ in the air using the UV absorption method. It is equipped with a high-efficiency O₃ scrubber and uses a coated sample tube and special materials to eliminate obstacles and prevent sample adhesion, allowing for the measurement of the minimum ozone amount.

All gas analyzers in the Vair series are equipped with a screen interface design that uses TFT-LCD and a touchscreen so that the user can operate the analyzer and maximize the visual image, and the MCU applied to the analyzer is a 32-bit ARM processor that operates based on Linux Kernel 2.6, maximizing system stability due to multiprocessing.

Additionally, the analyzer is equipped with an automatic zero correction system (Auto Zero) for smooth measurement and various interfaces (Ethernet, RS232, RS485, USB, DIO, analog output) for users to use it more comfortably and effectively.

FEATURES :

  • Ranges 0-0.1 / 0.5 / 1 ppm, user-selectable.
  • 7-inch touchscreen and TFT LCD interface.
  • Ethernet, RS-232, RS-485, and USB ports.
  • The USB interface is used for downloading stored data.
  • Temperature and pressure compensation and internal zero (optional)
  • The built-in data logger uses NAND-Flash to store up to 1 year (average data of 1 minute)
