DOG-2002 industrial dissolved oxygen meter DOG-2002 industrial dissolved oxygen meter is my company's high intelligence line continuous monitor. DOG-208 can be equipped with polarographic electrodes automatically from ppb to ppm level for a wide range of measurements, the detection of boiler feed water, condensate, the oxygen content of the liquid effluent and environmental protection industries such as special instrument measuring instrument features: All Chinese show convenient operation: full Chinese display, attractive interface: using high-resolution LCD module, all the data, status and operating tips are Chinese show no sign or code on their own definitions. Simple menu structure, text-based human form Dialogue: Compared with traditional instruments, DOG-2002 adds a lot of functionality, but thanks to the categories of the menu structure, method of operation is similar to the computer and use it more clear and convenient. Do not have to remember the steps and the order of operations; you can not manual, follow the prompts on the screen can be operated. Multiple parameters for display: shows the oxygen concentration value, the input current or output current, temperature, time and status on one screen simultaneously. The main display with 10 10mm Specifications Display oxygen concentration, eye-catching visual distance;?? 6 5 5 sub-display to the specifications of the display of the input current or output current, temperature, status, week, month, day and time every minute, etc. to meet the different habits and provide a time reference instrument users.
