CO Analyzer

The Vair-9003 CO analyzer accurately measures the minimum amount of CO in the air using a long-path curved optical mirror with high durability, employing the non-dispersive infrared analysis method (NDIR GFC). The Vair-9003 is equipped with a specially designed GFC wheel that prevents leaks over a long period of time and a stable infrared lamp (IR source).

All gas analyzers in the Vasthi 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 Cortex M4 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, analog output) for users to use it more comfortably and effectively.

FEATURES :

  • Ranges 0-50/100 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)
