Reliable for educational purposes
We bought several of these for our high school science lab. They hold up well to student handling and provide data accurate enough for our experiments. The price point makes it accessible for schools.

Excellent documentation and support
As someone new to pH sensing, I appreciated the clear wiring diagram and sample code provided. The module integrates easily into existing IoT dashboards. Highly recommended for students and makers.

Solid build quality
The BNC connector is secure, and the glass electrode seems durable. It handles continuous immersion in nutrient solutions well. Just remember to store the electrode properly when not in use to maintain longevity.

Works but requires patience
The sensor works as advertised, but getting stable readings takes some time and careful shielding of the analog wires to reduce noise. Once set up correctly, it performs well.

Good accuracy after calibration
Initially, the readings were a bit off, but once I followed the two-point calibration guide carefully, it became very accurate. The electrode feels sturdy, though the cable could be slightly longer for larger tanks.

Perfect for my hydroponic setup
This sensor module works flawlessly with my Arduino controller. The calibration process was straightforward using the included solutions, and the readings are consistent with my standalone meter. Great value for DIY projects.
Q: Is this waterproof or just the electrode?
A: Only the glass electrode probe is designed for submersion. The circuit board module itself is not waterproof and should be kept dry or housed in a protective enclosure.
Q: How often does the electrode need to be recalibrated?
A: For best results, we recommend calibrating the sensor every 2-4 weeks depending on usage frequency. If high precision is required, daily calibration before use is advisable.
Q: Can this sensor measure pH in hot water above 60°C?
A: No, the operating temperature range is specified as 0°C to 60°C. Exposing the sensor to temperatures higher than this may damage the electrode or affect accuracy.
Q: Does this kit come with storage solution for the electrode?
A: The kit includes calibration solutions (pH 4.01 and 6.86). For long-term storage, we recommend purchasing a separate 3M KCl storage solution to keep the glass bulb hydrated.
Q: Is the output digital or analog?
A: The module provides an analog output signal (0-5V) which corresponds to the pH value. You will need an ADC (Analog-to-Digital Converter) on your microcontroller to read the data.
