Good sensor, needs patience
Takes time to stabilize in the liquid. Make sure you calibrate it properly before first use. Otherwise, it works as expected.

Solid hardware
The module build quality is good. I wish the cable was a bit longer for my specific tank setup, but an extension works fine.

Perfect for my hydroponics setup
Calibration was straightforward using the included powder. The readings are stable after a minute or so. Great value for hobbyists.

Accurate readings
Compared with a professional lab meter and the difference was negligible. Very happy with the precision for the price point.
Q: Can I buy a replacement electrode separately?
A: Yes, the probe uses a standard BNC connector, so most generic pH electrodes with BNC connectors are compatible.
Q: How often should I calibrate the sensor?
A: For best accuracy, we recommend calibrating every 2 weeks or whenever the electrode has been stored dry for a long period.
Q: Is the electronic module waterproof?
A: The probe electrode is waterproof and can be submerged, but the electronic module board itself is not waterproof and should be kept dry.
Q: Does this support 3.3V logic boards?
A: Yes, it can work with 3.3V systems, but please ensure the power supply voltage matches the module requirements and check signal levels.
Q: Does it have automatic temperature compensation?
A: This module requires manual temperature compensation. You will need to measure temperature separately and adjust the pH value in your code.
