PH Electrode Probe BNC Connector E201-C
A pH sensor is a device that measures the hydrogen-ion activity in water-based solutions, which indicates how acidic or alkaline they are. It is commonly used to test the pH of liquids in various industries, such as chemical, pharmaceutical, and dye, as well as in scientific research.
Cautions:
- Before being measured, the electrode must be calibrated with a standard buffer solution of known PH value. In order to obtain more accurate results, the known PH value should be reliable, and closer to the measured one.
- When the measurement is completed, the electrode protective sleeve should be put on. A small amount of 3.3mol / L potassium chloride solution should be placed in the protective sleeve to keep the electrode bulb wet.
- The leading end of the electrode must be kept clean and dry to absolutely prevent short circuits at both ends of the output, otherwise, it will lead to inaccurate or invalid measurement results.
- After long-term use of the electrode, if you find that the gradient is slightly inaccurate, you can soak the lower end of the electrode in 4% HF (hydrofluoric acid) for 3-5 seconds, wash it with distilled water, and then soak in potassium chloride solution to make it new.

Frequently Asked Questions
How do I calibrate the E201-C pH probe?
Immerse the electrode in at least two standard buffer solutions (pH 4.01 and 7.00). Adjust your interface readings until they match the buffer values. Perform calibration before each measurement session for optimal accuracy.
Can I directly connect this probe to a Raspberry Pi?
The E201-C outputs an analog signal via its BNC connector. You’ll need a pH interface board or ADC module to convert this signal to digital before connecting to Raspberry Pi’s GPIO or I2C pins, along with the appropriate driver libraries.
How should I store the replaceable glass electrode?
After use, rinse the electrode with distilled water, then place it in the protective sleeve filled with 3.3 mol/L KCl solution. This keeps the glass bulb hydrated and maintains measurement stability over time.
