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.
