PGA500 online oxygen analyzer (micro) is used for on-line monitoring of oxygen concentration and output of 4~20mA signal in industrial field. It can be centralized controlled and monitored by DCS system or final control room.
Characteristic：
The device can be maintained through the operation of the switch valve and the sensor is protected. 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. It has current, relay alarm and RS485 output. Optional PC software, to realize the network of multi-channel measurement information display, storage.
