DOS-808A laboratory Dissolved Oxygen Meter
DOS-808A laboratory Dissolved Oxygen Meter is one of the electrochemical analyzers used in laboratory, a high-intelligence continuous monitor produced by our company. 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. It is portable and work at site with built-in lithium battery.
Features
Historical data: In measurement status, press the “Store” key, and the secondary meter will store the |
measured oxygen concentration value and temperature value automatically. |
Multi-parameter display: Display oxygen concentration value, input electric current, temperature, time, status |
simultaneously. |
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. |
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.
