Overview
The YUEFENG PHB-4 Portable acidity meter is a laboratory instrument with LCD display function, which can measure ph value, mV (ORP) and temperature parameters. Measurement ranges are 0~ 14.0 pH, -1999~ 1999mV and 0~ 80 ° C. It is designed to be portable and easy to carry.
Features
1. Portable design, easy to carry and use
2. LCD display function, intuitive reading
3. Multi-Parameter measurement: ph value, mV (ORP) and temperature
4. Measurement range: pH 0~ 14.0, mV -1999~ 1999, temperature 0~ 80 ° C
5. High Accuracy measurement: pH accuracy +/- 0.01pH, mV accuracy +/- 0.1% F.S, temperature accuracy +/- 1.0 ℃
6. Manual temperature compensation method
7. Undervoltage indication function to remind the power status
8. Flexible power supply: support 6V regulated power supply or 4 AA batteries
Principle
PHB-4 Portable acidity meter detects the concentration of hydrogen ions in the solution by Electrode, converts to ph value display; simultaneous measurement of Oxidation-reduction potential (mV) and temperature, combined with manual temperature compensation, to ensure measurement accuracy.
Steps
1. Install the battery or connect the regulated power supply
2. Turn on the instrument power switch
3. Measurement mode (pH, mV or temperature) as required
4. Electrode immersion in the solution to be tested
5. Measured values read on LCD display
6. Clean Electrode and Power Off After Use
Notice
• Make sure the power supply is sufficient before use, and pay attention to the undervoltage indication
• Electrode should be completely immersed in the solution during measurement to avoid contact with air
• Regularly calibrate instruments to ensure Measurement accuracy
• Use appropriate solvent when cleaning Electrode to avoid damage
• Electrode moisture during storage to prevent drying
• Avoid use in extreme temperatures or Humidity environments
