Overview
FANGZHOU FZ-670 is a 2-in-1 pH Electrode designed for special laboratory samples. It is suitable for measurement of mixed liquid samples, such as juice with no settling and good flowability after long-term storage, beer, milk, blood protein and alcohol.
Features
1. Measurement range: 0-14.00 pH.
2. Temperature range: 5-60 ° C.
3. Glass shell tube, sturdy and durable.
4. Adopt Ag/Agcl single salt bridge reference structure.
5. The liquid junction is a ceramic sand core salt bridge with stable performance.
6. The sensitive film is designed for bulbs.
7. The inner filling liquid can be replenished for easy maintenance.
8. Standard BNC interface, strong compatibility.
Principle
FZ-670 2-in-1 Electrode integrates pH-sensitive Glass electrode and reference Electrode. Its Glass bulb-sensitive film responds to the concentration of hydrogen ions in the solution, forming a potential difference; at the same time, the internal Ag/Agcl reference system provides a stable reference potential. The potential difference between the two is transmitted to the pH Meter through the BNC interface, and the pH value of the solution is directly displayed after conversion by the instrument.
Applications
Suitable for measurement of mixed liquid samples: juice, beer, milk, blood protein, alcohol.
Steps
1. Check Electrode Appearance and Filling Liquid.
2. Connect the Electrode BNC interface to the pH Meter host correctly.
3. Calibrate according to the instructions.
4. Electrode immersion in the sample to be measured.
5. After the measurement is completed, clean and store the Electrode as required.
Notice
Please read the instructions carefully before use.
• Make sure that the filling solution in the Electrode is sufficient and replenish it if necessary.
• Electrode bubbles and liquid junctions need to be fully immersed in solution for calibrating and measurement.
• Avoid prolonged use in strong acids, bases or extreme temperatures to prevent damage to the Electrode.
• Electrode should be cleaned with deionized water after use and stored as recommended.
• Do not use for measurement of samples containing solid particles or easy settling to prevent clogging of the liquid interface.
• Electrode is a precision part, please handle it with care to avoid collision.
