Overview
The Bante221-CN Portable pH Meter is a High Accuracy Portable pH Meter with Relative and Absolute mV Measurement modes, and 9 function parameters can be customized in the built-in system menu. The meter is suitable for outdoor measurement of pH and Oxidation-reduction potential of liquids. Measurement accuracy reaches 0.002pH.
Features
1. High Accuracy Portable pH Meter with Large Screen Backlit LCD.
2.1 to 5 point button calibrated to automatically identify pH standard buffer.
3. Optional pH buffer standard (USA/NIST/DIN) or 2 point custom calibrated.
4. Electrode slope display automatically prompts the user whether to replace pH Electrode.
5. Automatic temperature compensation to ensure accurate measurement within the full range.
6. Automatic calibration reminder, prompts the user to calibrate the meter regularly.
7. ORP mode supports 1 point offset calibrating, allowing adjustment of display values to known standards.
8. Relative and absolute mV modes provide accurate ORP readings.
9. Automatic end point lock, keep stable Measured value for easy browsing and recording.
10. Electrode diagnostics, check the zero offset and Electrode slope.
11. 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.
12. One-click reset (Reset) automatically restores the meter to the factory default settings.
13. Extended memory can store up to 500 sets of measurement data.
14. The built-in clock automatically marks the date and time of stored data to comply with GLP specifications.
15. USB Communication interface sends stored data to PC.
16. Multi-mode power supply solution (battery, Power Adapter, USB port of computer) to ensure smooth application of the instrument.
Principle
The Bante221-CN Portable pH Meter measures the pH value and Oxidation-reduction potential of liquids with pH Electrode and ORP Electrode, using automatic temperature compensation technology to ensure measurement accuracy. The built-in system supports custom parameter settings to optimize performance with calibrate and diagnostic functions.
Applications
Outdoor measurement of pH and Oxidation-reduction potential of liquids
Standards
GLP specification
Steps
1. Turn on the meter and select Measurement mode (pH or ORP).
2. Perform 1 to 5 point pH calibrating or 1 point ORP calibrating.
3. Immerse the Electrode in the liquid to be tested.
4. Measured value is stable, automatically or manually lock the data.
5. Store data or transfer it to a computer via USB interface.
Notice
• Measurement accuracy is regularly calibrated.
• Use the appropriate pH standard buffer to calibrate.
• Pay attention to the Electrode slope display and replace the aging Electrode in time.
• Avoid prolonged use in extreme temperature environments.
Make sure the power supply is sufficient and the battery lasts about 150 hours (when the backlight is turned off).
When storing data, pay attention to the date and time accuracy of the built-in clock markers.
