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. ## Frequently Bought Together - Extech EC150 Conductivity Meter - Apera Instruments AI1108 pH Calibration Buffer Solution Kit for pH/ORP Electrodes, 4.00 & 7.00 pH, 4 oz & 8 oz - EXTECH Instruments RE300 ExStik ORP Meter --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/258946331-ec150-conductivity-meter](https://www.desertcart.nz/products/258946331-ec150-conductivity-meter) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-09-19*
