Works well but needs careful handling

The sensor works as described, but the wires are a bit thin. I had to reinforce the connections. Otherwise, the data reading is reliable.

Excellent for prototyping

Bought five units for a university project. All of them performed consistently. The stainless steel probe is robust and suitable for long-term immersion.

Good accuracy after calibration

Initially, the readings were a bit off, but after calibrating with standard solutions, it became very accurate. The build quality of the probe feels durable.

5 FAQ

Q: What is the lifespan of the probe under continuous use?

A: Under normal conditions with regular cleaning, the probe typically lasts 1 to 2 years. Lifespan may vary depending on water corrosiveness and usage frequency.

Q: Is this sensor waterproof or just the probe?

A: The probe itself is waterproof and designed for immersion. However, the electronic module board is not waterproof and should be kept dry or housed in a protective enclosure.

Q: Where can I find the source code mentioned in the title?

A: A QR code and a download link are included in the product manual inside the box. You can also request the latest library version by contacting our support email.

Q: Does the package include the calibration solution?

A: No, the package includes the sensor module and probe only. Calibration solutions (1413 ppm and 12.88 mS/cm) need to be purchased separately for accurate tuning.

Q: Can I use this with a 5V Arduino Uno?

A: Yes, the module operates within 3.3V to 5.5V, so it is fully compatible with the 5V logic of an Arduino Uno. You can connect the AO pin directly to an analog input.
