Overview
The Bante920-CN Precision Laboratory pH Meter is a High Accuracy measuring instrument suitable for the measurement of pH value and Oxidation-reduction potential of samples. Measurement accuracy up to 0.002pH. The instrument is equipped with a large screen backlit LCD display, supports 5 point button calibrate, automatic information prompt, and built-in system menu to customize 9 function parameters.
Features
1. Precision Laboratory pH Meter with Large Screen Backlit LCD Display.
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. 1 point offset calibrated in ORP mode, 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. The one-click reset function 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.
Principle
Meter pH Electrode measurement of the pH value of the sample, and the use of automatic temperature compensation technology to ensure measurement accuracy. In ORP mode, 1 point offset calibrate and relative/absolute mV mode for Oxidation-reduction potential measurement. The system automatically diagnoses Electrode status, including slope display and zero point offset check to optimize performance.
Applications
Laboratory pH measurement, Oxidation-reduction potential measurement, water quality analysis, environment monitoring, industrial process control
Standards
GLP specification
Steps
1. Connect pH or ORP Electrode and Temperature Probe.
2. Turn on the meter and select Measurement mode (pH or ORP).
3. Perform 1 to 5 point calibrating using standard buffer or custom calibrating solution.
4. Immerse the Electrode in the sample and wait for the reading to stabilize.
5. Measured values are recorded using automatic or manual data locking.
6. Export and store data to the computer through the USB interface.
Notice
• Periodically calibrate the meter to ensure Measurement accuracy.
• Clean Electrode after use and store properly.
• Avoid Electrode Exposure to Extreme Temperatures or Chemicals.
• Check Electrode slope display and replace aging Electrode in time.
• Note that there is no operating time setting in automatic shutdown mode.
Make sure the USB connection is stable when exporting data.
