Overview
The Bante221-ORP is a Portable pH/ORP meter with High Accuracy measurement capability, pH and Oxidation-reduction potential (ORP) measurement for outdoor liquid detection. The meter has a built-in system menu with customizable parameters, Measurement accuracy up to 0.002pH, and a large screen backlit LCD display.
Features
1. High Accuracy Portable pH Meter with Large Screen Backlit LCD.
2. The pH mode supports 1 to 5 point button calibrating, and automatically recognizes the 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 Portable pH/ORP meter detects the pH value and Oxidation-reduction potential of liquids by electrode, using automatic temperature compensation technology to ensure measurement accuracy. In pH mode, the meter automatically recognizes buffers and calibrates; in ORP mode, relative and absolute mV measurements are supported, and the display value is adjusted by calibrating points. The system has built-in automatic diagnostics to monitor Electrode status and performance.
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 calibrating: pH mode uses 1 to 5 point buttons to calibrate to automatically identify the buffer; ORP mode calibrates with 1 point offset.
3. Electrode is immersed in the liquid to be tested, and the meter automatically locks the stable Measured value.
4. Export and store data to the computer through the USB interface.
5. Use the one-click reset function to restore the default settings.
Notice
• Measurement accuracy is regularly calibrated.
• Pay attention to the Electrode status and replace the Electrode in time according to the slope display prompt.
• In the automatic shutdown mode, the meter will automatically shut down after no operation to save power.
When using multi-mode power supply, ensure that the Power Adapter or USB connection is stable.
When storing data, the built-in clock automatically marks the date and time, subject to GLP specifications.
