## Questions & Answers

**Q: Does it come with a calibration certificate?**
A: No. You manually calibrate it using distilled water.

**Q: Can I use this to measure salt levels in my pool?**
A: The measurement may be inaccurate because the salinity of the swimming pool is not good and our products are generally used to test seawater.

**Q: can i calibrate this with RODI water?**
A: Sorry for the last answer, the one I bought came with olive oil or honey instructions but in this one description you can see they recommend distilled water (same RODI parameters )to calibrate it, so you can do it.

**Q: what battery does it use?**
A: It does not require a battery.
