## Description

Review: Surprised - Excellant and reliable. (My first refractometer from desertcart was a dud, compete waste of money and a way out of calibraton.) This unit came calibrated. Not only that, I've not had to re-calibrate after numerous uses. Its as good as the refractomerter my aquarium store uses upon actual side by side comparison. I like the little pipettes that came with it... handy. I am surprised how good this unit really is. I have a salt water aquarium and make my own RODI water.
Review: Good for the price - Worked as intended and easy to use. The cleaning cloths and extra droppers were a nice addition.

## 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.
