Description

GWQ-DO290详情_01.jpg

GWQ-DO280 Dissolved Oxygen Meter is one of the intelligent online chemical analysis instruments. It is widely used in continuous monitoring of dissolved oxygen, saturation, oxygen partial pressure and temperature .The continuous monitoring data is realized by remote transmission monitoring and recording through the transmission output connection recorder. It can also be connected to the RS485 interface and can be easily connected to the computer for monitoring and recording through the MODBUS-RTU protocol.


Application

 It is widely used in continuous monitoring of dissolved oxygen, saturation, oxygen partial pressure and temperature in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water solutions.
