DOG-209 Intelligent On-line Dissolved Oxygen Meter is one of the intelligent on-line chemical analyzers developed by our company. It has strong environmental adaptability, clear display, easy operation and excellent measuring performance with high performance-price ratio. It can accurately measure the dissolved oxygen value and temperature of solution. It can be widely used in such fields as thermal power plants, chemical industry, chemical fertilizer, metallurgy, environmental protection, pharmacy manufacturing, biochemistry, foodstuff and running water etc.

Features

Intelligent: DOG-209 Intelligent On-line DO Meter adopts high-precision AD conversion and single chip

microcomputer processing technologies and can be used for measurement of the DO value and temperature,

automatic temperature compensation and self-checking etc function.

High protection grade: It adopts waterproof and dust-proof design and is applicable for outdoor use. (With a

protection grade of IP65)

Multi-parameter display: The DO value and temperature values can be displayed on the screen at the same time.

It adopts LED display module with high brightness. The main display shows the DO value in red color and in a

10 x 10mm size. As the main display is eye-catching, the displayed values can be seen from a long distance away.

Communication interface: It can be easily connected to a computer to perform monitoring and communication.
