Solid build quality
The refillable electrode is a nice touch for longevity. Cable could be longer.

Good value sensor
Works well with Arduino. Calibration solution not included so buy separately.
5 FAQ
Q: Can this measure soil pH?
A: This probe is designed for liquid solutions. For soil, create a slurry with distilled water.
Q: What calibration solutions are required?
A: Standard pH 4.01 and pH 6.86 buffer solutions are recommended for calibration.
Q: Is the probe replaceable?
A: Yes, the probe uses a standard BNC connector and can be replaced independently.
Q: Is this compatible with 3.3V logic?
A: The module operates at 5V. Use a level shifter for 3.3V microcontrollers.
Q: How do I store the probe when not in use?
A: Store the probe in 3M KCl solution to keep the electrode hydrated.
