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 EC500 Waterproof ExStik II pH/Conductivity Meter - pH Buffer Calibration Solution Kit 3-Pack: pH 4.00, pH 7.00, pH 10.00 Buffers — 250 ml (8.4 fl oz) Each — Color Coded — NIST Traceable for All pH Meters - Oakton AO-00653-18 Oakton Conductivity and TDS Standard, 1413 Μs; 500 mL --- ## 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.tw/products/7003674-extech-ec500-waterproof-exstik-ii-ph-conductivity-meter-5-parameters](https://www.desertcart.tw/products/7003674-extech-ec500-waterproof-exstik-ii-ph-conductivity-meter-5-parameters) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-07-11*
