DOG-1902 Industrial Dissolved Oxygen Meter has special price advantages due to its simplified functions on the premise of guaranteed performance. The clear display, simple operation and high measuring performance provide it with high cost performance.

It can be widely used for continuous monitoring of the dissolved oxygen value of the solution in thermal power plants, chemical fertilizer, metallurgy, environmental protection, pharmacy, biochemical engineering, foodstuff, running water and many other industries. It can be equipped with Polarographic Electrode and can do ppm level measurement.

Features
DOG-1902 is a precision instrument used for testing and control of dissolved oxygen. The instrument has all the
parameters for microcomputer storing, caluating and compensating of the related measured dissolved
oxygen values; DOG-1902 can set the relevant data, such as elevation and salinity.

It is also featured by complete functions, stable performance and simple operation. It is an ideal instrument in the field of the dissolved oxygen test and control.

DOG-1902 adopts the backlit LCD display, with error indication. The instrument also owns the following features: automatic temperature compensation; isolated 4-20mA current output; the dual-relay control; high and  low points alarming instructions; power-down memory; no need back-up battery; data saved for more than a  decade.
