Overview
The Bante920 Precision Laboratory pH Meter is a multifunctional laboratory instrument suitable for the measurement of pH and Oxidation-reduction potential of samples. Measurement accuracy up to 0.002pH. Equipped with a large screen backlit LCD screen, supports 5 point button calibrating and automatic information prompts, and the built-in system menu can 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. ORP mode supports 1 point offset calibrated and relative and absolute mV modes.
8. Automatic end point lock, keep stable Measured value for easy browsing and recording.
9. Electrode diagnostics, check the zero offset and Electrode slope.
10. The system menu can customize 9 function parameters such as the number of calibrated points and Stability standards.
11. The one-click reset function automatically restores the meter to the factory default settings.
12. Extended memory can store up to 500 sets of measurement data.
13. The built-in clock automatically marks the date and time of stored data to comply with GLP specifications.
14. USB Communication interface sends stored data to PC.
Principle
The meter detects the pH and Oxidation-reduction potential (ORP) of the sample by Electrode, and uses automatic temperature compensation and Electrode slope display in pH mode to ensure measurement accuracy. In ORP mode, accurate readings are provided by offset calibrate and mV mode. The system automatically locks the stable Measured value and supports Data storage and transfer.
Applications
Laboratories, scientific research institutions, industrial testing
Standards
GLP specification
Steps
1. Connect Electrode and turn it on.
2. Select Measurement mode (pH or ORP).
3. Perform calibrating: pH mode supports 1 to 5 point calibrating, ORP mode supports 1 point offset calibrating.
4. Set the temperature compensation mode (manual or automatic).
5. Start measurement, the meter automatically locks the stable value.
6. Transfer data to the computer through the USB interface.
Notice
• Periodically calibrate the meter to ensure Measurement accuracy.
• Pay attention to the Electrode slope display and replace the aging Electrode in time.
• Avoid use in extreme temperature environments.
• Clean Electrodes after use and store them properly.
• Data logging according to GLP specifications.
