Well, city, salt. If it has nitrates in it this checker will see them. Only complaint is it doesn’t come with a lot of reagent packs and they are hard to come by currently. But it is absolutely a great investment for accuracy and peace of mind. **Q: Will this measure .25 nitrates?** A: Yes **Q: Can I add some marine salt to my freshwater sample to make this work for freshwater?** A: Go on to Reef2reef discussion boards and direct your question to Randy Holmes Farley he's the chemist. He usually gets back to you fairly quickly. My honest answer though, you'd be better off with Tetra strips. They're plenty accurate enough for fresh water applications and cheap enough. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Optimal *by W***N on 11 March 2025* ### ⭐⭐⭐⭐⭐ Another excellent Hanna product! *by C***T on 11 June 2025* ### ⭐⭐⭐⭐⭐ Just excellent! *by M***C on 24 January 2026* ## Frequently Bought Together - Hanna Instruments High Range Nitrate Checker HI782 - WLR Industries Hanna HI774 Phosphate Ultra Low Range Colorimeter for Marine and Saltwater appllications Phosphate checker - Hanna Instruments Hanna Marine Magnesium Checker HC HI783 Saltwater Aquariums, Marine, Aquaculture Applications Magnesium Tester 64 grams --- ## 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.pl/products/369052011-high-range-nitrate-checker-hi-782](https://www.desertcart.pl/products/369052011-high-range-nitrate-checker-hi-782) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-21*
