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 ### ⭐⭐⭐⭐⭐ Large Easy to Read and Accurate *by H***5 on April 19, 2026* Excellent Salt water tester Accurate Very Easy to Read Large print I use it on my Koi pond Extremely useful So Far so good had other ones they were good But I can see this one much better Definitely recommend ### ⭐⭐⭐⭐⭐ Very easy to use and gives accurate readings *by S***E on December 19, 2023* I changed from a Hayward T3 salt cell to a generic brand.

I dry it off before I put the cap on and put it away. ### ⭐⭐⭐⭐ Reasonable Product for pond *by R***L on March 22, 2023* This is simple to use for a pond, but you need to know your variables for your pond to be able to use it. We use it to keep our Koi pond at .1% salinity. There is an accuracy margin that makes this difficult to be 100% certain, but we have pond plants that are a very good indicator too. We also keep it in the water for a couple minutes when there's a big difference between air temp and pond temp to be sure the temp reading is as accurate as possible. If we do it too fast, we can be off by .02%+. In 8 months, it has maintained its calibration and performed consistently. We make sure to rinse with distilled water and use a paper towel to soak up extra water drops without touching the nodes to ensure no buildup affects the readings. I do not fully submerge it. I have excellent water flow so the full pond volume moves through the waterfall 2-3× per hour though. Not all ponds are equal. This has worked very well for us, but if you have a slow pump, I recommend getting a sample in a cup/bucket on a stick to get a sample from bottom to top and measuring that. I get consistent readings in the waterfall and any spot of my pond. The temp is accurate to my pond thermometer within a minute or two. With winter, the meter is as warm as the house then I put it in 40°F or colder water, it needs a minute or so. In late summer when water and air were about the same still, it was pretty instantaneous. We also do the math on paper when changing water and adding salt back. Dual checks are important to preserve plant life and protect the fish. We might buy a more expensive salinity only someday, but you can be diligent and use this to *verify your results. You shouldn't ever blindly use a meter with living things. Always calculate by pond volume too. It's just what you do to be certain. Ther isn't a simple way to use salt in a pond. But there is a simple way to check on your results! ## Frequently Bought Together - 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 - HTH 52047 Swimming Pool Care Salt Shock, Stabilized Chlorinator, 1 dose Treats 10000 gallons, 5x12oz Packets - Intex Krystal Clear Saltwater System for Above-Ground Pools up to 15,000 Gallons --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/648105508-digital-salinity-tester-for-salt-water-waterproof-ip67-salinity-meter](https://www.desertcart.tn/products/648105508-digital-salinity-tester-for-salt-water-waterproof-ip67-salinity-meter) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-06*
