Overview
The PHB-5 is an economical pen pH Meter manufactured under the brand BANTE. Compact and portable, it is suitable for quick pH value measurement in the field. The instrument features pH and temperature measurement and supports automatic temperature compensation to provide reliable measurement results.
Features
1. Support 2 point button calibrate, and automatically identify pH standard buffer, simplify the calibrating process.
2. With data lock function, you can manually press the button to instantly retain the current Measured value.
3. With an automatic shutdown function, the power is automatically turned off after 8 minutes of no operation, effectively saving battery energy.
4. Adopting a replaceable Electrode design helps to reduce the long-term maintenance and use costs of the instrument.
Principle
The PHB-5 Pen pH Meter senses the activity of hydrogen ions in a solution through its pH Composite Electrode and converts it to the corresponding potential difference. The circuitry inside the instrument measures this potential difference and calculates and displays the pH value of the solution based on the built-in calibrated Linear dispersion and automatic temperature compensation data. At the same time, the built-in temperature sensor measures the temperature of the solution to compensate for the pH Measured value for improved accuracy.
Applications
Water quality testing, laboratory analysis, education and research, aquaculture, agricultural soil testing, Food processing, environmental monitoring
Standards
No specific compliance criteria were mentioned in the data.
Steps
1. Turn on the instrument power.
2. Electrode clean with deionized water and blot dry with filter paper.
3. Electrode is immersed in a standard buffer with known pH value for calibrating (two point calibrating is supported).
4. After calibrating, clean the Electrode and blot dry, immerse in the solution to be tested.
5. Wait for the reading to stabilize, you can directly read the ph value, or press the lock key to keep the current Measured value.
6. After the measurement is completed, clean the Electrode and store it properly.
Notice
• Do not use in strong acid, alkali or corrosion solution for a long time.
• Electrode bubble and reference fluid interface clean before calibrating and measurement.
• When the instrument is not in use for a long time, please remove the battery.
• Electrode is a wearing part and needs to be replaced regularly according to the usage.
• Avoid severe vibration or falling of the instrument.
• Do not use in excess of the specified Ambient Temperature (0~ 50 ℃).
