So if you know the water is in the range of 35ppt, you can't make direct measurements. But, you could dilute the sample (say 10x) in the field using bottled water (has a salinity <<< sample) or DI water and that would put you at 3.5g/L roughly. You should be able to detect fluctuations at 0.1ppt on the diluted water which translates into detecting 1ppt fluctuations in the water. **Q: is the Exstick EC500 come with calibration certificate ?** A: No, it does not, but we can get you a Certificate of Conformance from Extech, when you purchase this product from our Amazon Store. **Q: how does it give two readings** A: Salinity in ppm Conductivity. And total dissolved solids. I really like this meter. Used it for jar tests this summer **Q: Can this be used in soil?** A: Hi This product can not be used in soil. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great piece of kit *by on Reviewed in the United Kingdom 23 December 2024* Great piece of kit for my work.Just remember to follow the calibration instructions 👍 ### ⭐⭐⭐⭐⭐ Great *by on Reviewed in the United Kingdom 16 October 2019* Item as described!!! ### ⭐⭐⭐⭐ Four Stars *by on Reviewed in the United Kingdom 4 April 2015* It is doing pretty well.
