The pillows are also over sized and less convenient to use then Hach. The Hach reagent works with this unit just make sure it's the 10ml pillows. **Q: How many ppm of free chlorine will this read up too** A: Range 0.00ppm - 2.50 PPM Thank you:) **Q: Do you have to calibrate it before every single use or does one calibaration lasts a while ?** A: You can buy a calibration kit for this. It's cheap. It has a clear vial and a pink vial that should read 1.00 and I check it every few months to make sure its still close. Same steps as a normal residual check The steps for every time you check the chlorine residual include a 'calibration' to the clear water before adding the packet. Step one turn it on, shows C-1 Step two fill the vial with water and put it in and press the button Step three, after it says C-2, take the vial out and add the packet. Step four put it back it after a shake and press the button. Done. **Q: The product data pdf provided in this listing states the Hanna analysis devices are manufactuered in their new state of art European plant. Correct?** A: Yes ## Frequently Bought Together - Hanna Instruments HI701 Checker HC Handheld Colorimeter for Free Chlorine - Hanna Intruments HI93701-01 Chlorine Reagents - Hanna Instruments HI 711 Checker HC Handheld Colorimeter, For Total Chlorine --- ## 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.vu/products/733536588-hanna-instruments-hi701-checker-hc-handheld-color-meter-for-free](https://www.desertcart.vu/products/733536588-hanna-instruments-hi701-checker-hc-handheld-color-meter-for-free) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-18*
