The appearance of the instrument

The appearance and components of the instrument are shown below.

WQO series of monitors by the instrument host, composite dissolved oxygen electrode, ph electrode, salinity electrode or ammonia nitrogen, ORP electrode composition. The electrode system uses the measurement of sensitive dissolved oxygen composite electrode, ph electrode and salinity electrode automatic temperature compensation, reliable measurement, accurate data.

main feature

All Chinese display, easy to operate: the use of high-resolution LCD module, all data, status and operating tips are Chinese display, there is no manufacturer's own definition of symbols or code.

Multi-parameter simultaneous display: on the same screen can also display the oxygen concentration value, ph, ammonia nitrogen, temperature and state. Display with 128 × 64 dot matrix LCD, with eye-catching, visual distance and so on.

The main function

Backlight function: can be used in the dim or completely lightless environment, the brightness of the backlight can be adjusted by software, so that the display is always clear.
