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? - 🛒 **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.hu/products/22974785-extech-ec150-conductivity-tds-and-temperature-meter-waterproof-pen](https://www.desertcart.hu/products/22974785-extech-ec150-conductivity-tds-and-temperature-meter-waterproof-pen) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-10-05*
