CX-LDO-1605 Chinese Desktop Dissolved Oxygen Meter is one of the electrochemical analyzers used in lab and produced by our company and a high-intelligence continuous monitor. It can be equipped with the DOS-808F Polarographic Electrode, achieving a wide range of automatic measurements from ppb level to ppm level. It is a special instrument used for testing the oxygen content of the solutions in the boiler feed water, condensate water, environmental protection sewage and other industries.

 

Features:  

Historical data: In times of measurement, press the “Store” key, and the secondary meter will store the

measured oxygen concentration value and temperature value automatically; it can store 3000 groups of data.

Notepad: It records the operation of the instrument and the time of occurrence faithfully, convenient for

Management.

Electrode analysis: It stores calibration modes, time and results for 50 times in order to analyze the changes of

electrode.

Clock: It displays the current time to provide the time reference for the recording.

Backlight: It can be used in dim light or complete darkness; according to temperature changes, the contrast can

be adjusted automatically, so that the display is made always clear.

Industrial control watchdog: It ensures that the instrument won’t break down as the basic requirement on the

instrument.

Four calibration modes: In addition to the traditional one-point and two-point calibration, there are also manual

zero point and slope inputs as well as the known oxygen concentration value calibration and other methods to

meet the needs for the use in all circumstances.
