CO2 Analyzer
Vair-9021 CO2 Analyzer is the analyzer that measures minimum amount of CO2 in air correctly through the optical curved mirror which has long light path and durability, using the Non-disoersive Infrared Analysis Method (NDIR GFC). Vair -9021 is equipped with the specially designed GFC wheel with no leak for a long time and the stable infrared lamp (IR Source).
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 automatic zero correction system (Auto Zero) for smooth measurment and various intereface (Ethernet, RS232, RS485, USB, Analog out) so that user can use it more conveniently and usefully
FEATURES :
- Ranges : 0-5% or 0-30% CO2 (dual channels for ambient monitoring)
- 7inch TFT LCD & touch screen interface
- Ethernet, RS-232, RS-485 & USB ports.
- USB interface utilizes for Stored Data Download.
- Temperature & pressure compensation and Internal zero (optional)
- In built Data Logger Utilizes NAND-Flash to store up to 1year (1 min averaged data)
