PGA520 online carbon dioxide analyzer is used for long-term online monitoring of oxygen concentration and output of 4-20mA signal in industrial field, and DCS system or final control room centralized control and monitoring.
Characteristic：
Infrared principle sensor
The choice of AC / DC power supply is designed with lightning protection.
The precision circuit amplifier, with the temperature compensation, is used to measure the gas quickly and accurately.
The structure of the whole machine is a solid shell of aluminum and magnesium alloy, and the protection grade of IP67.
With current, relay alarm and RS485 output, through the supporting PC software.
The network can realize the display and storage of multi-channel measurement information.
