DOG-3082 industrial dissolved oxygen meter DOG-3082 industrial dissolved oxygen meter is my company's latest generation of (English) text microprocessor-based high-end instruments, with the (English) text display, the (English) text menu-driven operation, the whole intelligent, multi-functional, high measurement performance, environmental adaptability and other characteristics. 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, water and other liquids and environmental protection industries in the special instruments to measure the dissolved oxygen content. Instrument features: The new layout, cast aluminum housing, metallic, create high-quality E era of water meter! All Chinese display, easy to operate: All the (English) text display, attractive interface: using high-resolution LCD module, all the data, status, and operating tips are in the (English) text display, there is no definition of the manufacturers themselves symbol or code. Simple menu structure, text-based human form Dialogue: Compared with traditional instruments, DOG-2082 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 shows the oxygen concentration in 10x10mm size value, smart, visual distance; six sub-display with 5x5 specification display or output current of the input current, temperature, status, week, month, day and time every minute, in order to meet users' different habits and provide a time reference instrument.
