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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***E on 19 December 2023* I changed from a Hayward T3 salt cell to a generic brand.
