DOG-209 Industrial dissolved oxygen analyzerDetailed product description：

DOG-209 Industrial Dissolved Oxygen Analyzer

The DOG-209 intelligent online DO meter adopts high-precision AD conversion box microcontroller microprocessor technology, which can complete various functions such as DO measurement, temperature measurement, temperature automatic compensation, instrument self check, etc
High protection level: Waterproof and dustproof design, suitable for outdoor use (protection level: IP65)
Simultaneous display of multiple parameters: Display DO value and temperature simultaneously on one screen. Adopting high brightness LED display module, the main display displays DO value in red 10x10 specifications, which is eye-catching and has a long visible distance
Communication interface: Can be easily connected to a computer for monitoring and communication
