Overview
The Bante903-UK Precision pH/dissolved oxygen meter is a Multi-Parameter Laboratory Water Quality Analyzer with a large screen backlit LCD display. The meter integrates pH, Oxidation-reduction potential (ORP) and dissolved oxygen concentration and Saturation measurements. The built-in system menu allows users to customize 11 functional parameters for accurate analysis of various liquids.
Features
1. Multi-Parameter measurement function can simultaneously detect pH, ORP and dissolved oxygen.
2.1 to 5 point pH calibrated, automatically recognizes standard buffer, supports USA/NIST/DIN standard or custom calibrated.
3. ORP mode provides 1 point offset calibration, supports relative and absolute mV measurement.
4. The dissolved oxygen mode supports 1 or 2 point calibrating, with salinity and atmospheric pressure compensation functions.
5. Automatic temperature compensation, calibrating reminder, end point lock and Electrode diagnostic function.
6. The system menu can customize 11 parameters such as calibrating point, Stability standard, and data locking mode.
7. One-click reset function to quickly restore factory settings.
8. Extended memory stores 500 sets of data, and the built-in clock conforms to GLP specifications.
9. USB Communication interface facilitates data transfer to computer.
Principle
The meter is measured by connecting a dedicated Electrode (e.g. pH Electrode, dissolved Oxygen electrode). In pH mode, the pH value is calculated using the potential difference between the Electrode and the solution, and temperature compensation is automatically performed; ORP mode measurement Oxidation-reduction potential is ensured by calibrating accuracy; dissolved oxygen mode uses Electrode method, combined with salinity and atmospheric pressure compensation, to accurately determine oxygen concentration and Saturation. Automatic locking function ensures that the reading is recorded after stability.
Applications
Laboratory water quality analysis, environment monitoring, industrial process control, education and research, aquaculture, wastewater treatment
Standards
GLP specification
Steps
1. Connect the corresponding Electrode (such as pH Electrode or dissolved Oxygen electrode) to the meter.
2. Turn on the power and select Measurement mode (pH, ORP or dissolved oxygen).
3. Perform calibrating: pH mode uses standard buffer for 1-5 point calibrating; ORP mode for 1 point offset calibrating; dissolved oxygen mode uses air saturated water or zero oxygen solution for 1-2 point calibrating.
4. Immerse the Electrode in the liquid to be tested and wait for the reading to stabilize.
5. Measured values are automatically locked and data is recorded or stored.
6. Use the USB interface to transfer and store data to the computer.
Notice
• Regularly calibrate the meter to ensure Measurement accuracy, calibrate reminder function can be set for 1-31 days.
• Check Electrode status before use, automatic Electrode diagnostic function can view zero and slope.
• Salinity and atmospheric pressure compensation are required for dissolved oxygen measurement.
• Avoid exposure of Electrode to air for a long time and clean it promptly after use.
• The meter supports automatic shutdown, which can be turned off 10, 20 or 30 minutes after no operation to save power.
When storing data, pay attention to the built-in clock mark, which meets the requirements of GLP specifications.
