## Questions & Answers

**Q: Will this work on salt (ocean) water (not continuously submerged)?**
A: Depends on the tds level of the water. This meter only goes up to 1000 ppm. If the water is higher than that it won’t read it correctly

**Q: Can this be left submerged permanently?**
A: If you talk about the sensor itself, I would say yes. Depends a bit on the salinity of the fluid you are measuring. Sea water will destroy everything given enough time. Potable water should be OK.

**Q: Can i use this sensor an esp32 board? the example code is for arduino uno**
A: Yes it works just fine with an ESP 32. the example code works as well for the esp 32

**Q: Does this come with any calibration solutions or what is recommended for calibration?**
A: it does not. Also, it only reads up to 1000ppm, so its ok for water quality testing, but not hydroponics nutrient solution.
you can buy calibration solution on amazon
