## Description

Digital Salinity Tester for Salt Water - Waterproof IP67 Salinity Meter with ATC Large Range 0-200ppt Saltwater Tester for Seawater, Aquariums, Marine Monitoring, and Koi Fish Pond by ORAPXI

Review: I changed from a Hayward T3 salt cell to a generic brand. The new salt cell works fine but it would not calibrate to the actual salt readings. I bought this to use and found it matched my pool stores reading exactly. Very easy to use. I dry it off before I put the cap on and put it away.
Review: This item is essential if you have a Koi pond. It is very easy to use and is very accurate.

## Questions & Answers

**Q: Does this measure salt (NaCl) or sodium (Na) ?**
A: It measures salt (sodium chloride).

**Q: What calibration and conductivity solution do I use ?**
A: ORAPXI salinity meter has 3-point-calibration, which means you can calibrate the meter with 1413 μS/cm, 12.88 mS/cm, 111.8 mS/cm solution seprately.
Depending on your application needs. If you test hydroponic nutrient, the tester need to be calibrated 1413 μS/cm solution. If you test saltwater pool, the tester need to be calibrated 12.88mS/cm solution. If you test aquarium tank, the tester need to be calibrated 111.8 mS/cm solution. If you test all application, the tester need to be calibrated 1413 μS/cm, 12.88 mS/cm, 111.8 mS/cm calibration solution.
All calibration solutions can be purchased at Amazon by searching for "1413 μS/cm calibration solution"，"12.88 mS/cm calibration solution", "111.8 mS/cm calibration solution".

The calibration steps are as follows：
a) Prepare 1413 μS/cm standard solution, press POWER button to turn it on.   Insert the tester compound electrode into the standard solution;
b) Press MODE/CAL button, adjust the tester to EC mode, the word “μS/cm” will be displayed at the left top of the screen.
c) Press MODE/CAL about 4 seconds, then release the button, the “CAL” symbol will display, then a value will flash 3 times on the screen, when the value starts to flash, press down button( If the flashing value is higher than 1413μS/cm ) or up button ( If the flashing value is less than 1413μS/cm ) to adjust the reading toward 1413μS/cm.
d) After adjust the displaying value to 1413 μS/cm, then release the button, waiting the reading stop flashing, the calibration is finished.
The 12.88 mS/cm and 111.8mS/cm solution calibration is the same as above procedures.

**Q: Does this measure salt (NaCi) or sodium (Na) ?**
A: Measures salinity.  I use to measure the salinity in my reef tank.

**Q: can this unit also show Celsius**
A: Yes, I believe it does, though it isn't sitting in front of me at the moment.  I have found this perfect for my 600 gallon goldfish pond.
