Overview
The Bante821 Portable dissolved oxygen meter is a High Accuracy Portable instrument for outdoor measurement of dissolved oxygen concentration and percentage Saturation of samples. Measurement accuracy is 0.2 mg/L. It has 1 or 2 point button calibrated, automatic end point locking function, and built-in system menu can customize 9 function parameters.
Features
1. High Accuracy Portable dissolved oxygen meter with large backlit LCD screen.
2.1 or 2 point button calibrated, using air saturated water or zero oxygen liquid.
3. Manual salinity and atmospheric pressure compensation to ensure accurate measurement within the full range.
4. Automatic temperature compensation, eliminate measurement deviation at different temperatures.
5. Automatic end point lock, keep stable Measured value for easy browsing or recording.
6. The system menu can customize 9 function parameters such as the number of calibrated points, Stability standard, Display resolution, Data lock mode, and automatic shutdown mode.
7. One-click reset (Reset) automatically restores the meter to the factory default settings.
8. Extended memory can store up to 500 sets of measurement data.
9. The built-in clock automatically marks the time and date of stored data to comply with GLP specifications.
10. USB Communication interface sends stored data to PC.
11. Multi-mode power supply solution (battery, Power Adapter, USB port of computer) to ensure smooth application of the instrument.
Principle
The Bante821 Portable dissolved oxygen meter detects dissolved oxygen concentration in water samples with a dissolved Oxygen electrode, combined with automatic temperature compensation, manual salinity and atmospheric pressure compensation to ensure measurement accuracy. The automatic end point locking mechanism retains the value after the measurement is stabilized for easy recording and analysis.
Applications
Research and education, aquaculture, water and wastewater treatment, ponds and aquariums, surface and groundwater testing, and other industrial applications
Standards
GLP specification
Steps
1. Use 1 or 2 point button to calibrate, choose air saturated water or zero oxygen liquid.
2. Manual salinity and atmospheric pressure compensation settings.
3. The instrument automatically performs temperature compensation and measurement.
4. Measured value is read after automatic end point lock.
5. Send the stored data to the personal computer through the USB interface.
Notice
• The calibrated reminder can be set for 1 to 31 days or turned off, and needs to be checked regularly.
• The battery life is about 150 hours (when turning off the LCD backlight), pay attention to replacing the battery in time.
• Electrode cleaning after use to avoid contamination affecting Measurement accuracy.
• Operate within the specified temperature compensation range (0~ 50 ° C) to ensure accuracy.
• The data storage capacity is 500 sets to avoid data loss beyond the limit.
