Overview
A181 Precision dissolved oxygen meter is a laboratory instrument of BANTE brand, suitable for determining the dissolved oxygen concentration and percentage Saturation of samples. The instrument uses 1 or 2 point button calibration, supports air saturated water or zero oxygen liquid Calibration method, Measurement accuracy up to 0.2mg/L, and has 1000 sets of data storage capacity.
Features
1. Equipped with a 7-inch TFT display
2.1 or 2 point button calibrate, support air saturated water or zero oxygen liquid calibrate
3. salinity and atmospheric pressure compensation function
4. Automatic temperature compensation
5. Alarm limit function
6. Stability icon tips
7. Automatic end point locking
8. Interval reading mode
9. Password protection
10. Extended memory can store 1000 sets of data
11. USB Communication interface
12. One-click reset function
Principle
The instrument detects the dissolved oxygen concentration in the sample through the dissolved Oxygen electrode, uses automatic temperature compensation to eliminate the temperature effect, and ensures the full scale measurement accuracy through salinity and atmospheric pressure compensation. The measurement data is displayed on the display screen after processing, and can be Data storage or transmission according to the settings.
Steps
1. Connect the power supply and dissolve Oxygen electrode
2. Select 1 or 2 point Calibration method
3. Use air saturated water or zero oxygen liquid for calibrating
4. Measurement parameters (such as salinity, pressure compensation, etc.)
5. Electrode immersion in the sample to be tested
6. Read and record measurement results
7. Optional interval reading mode for continuous monitoring
Notice
• Before calibrating, make sure to use the correct calibrating liquid (air saturated water or zero oxygen liquid)
• Electrode is fully immersed in the sample during measurement
• Regularly check Electrode Membrane Cap and Filler Status
• Avoid use in environments beyond the specified Temperature range
• Electrode cleaning immediately after use
• The calibrated reminder function is recommended to be set regularly
• Password protection prevents unauthorized changes to settings
