Product Description
RDB20 type DO meter for waterproof design, is for the home aquarium, school teaching experiment, aquaculture and other special development, cost-effective. Using the latest micro computer circuit, automatic calibration, automatic temperature compensation, 10 minutes automatic shutdown. DO value and temperature for measuring solution.
HOW TO USE
1 before the use of dissolved oxygen, the membrane of the electrode should be set, and the electrolyte is added to the dissolved oxygen pen. After 10 minutes of dissolved oxygen will automatically shut down.
2 press the [ON/OFF] button to open the power switch, the dissolved oxygen pen is still placed in the air, the [CAL] key to enter the full calibration state, the instrument at the temperature position will display a flashing "100" interface, waiting for 3-5 minutes after a row of data is stable, according to [YES] key to determine the data. Press a [YES] button to enter the measurement state directly.
3 the dissolved oxygen pen is cleaned and put into the liquid, and the water to the temperature sensor (Yin Shailiang's metal part) but not the probe (yellow cap) is not without probe. The value of the display is the DO value of the solution. Measure is finished, press [ON/OFF] key 3 seconds off power source.
4 if the long time is not, please set the film set spin, clean the electrode with distilled water inside and the film set, after the film set to dry electrode.
