Which I thought I misplaced on a job site, and then found the day after this one arrived !! ### ⭐ it appears this $80 tool out of the box is no better, or perhaps even worse *by on Reviewed in the United States 19 March 2018* A cheaper-feeling device than what I imagined. Its accuracy is questionable, and without paying extra for the calibration materials, I'll never know for sure. I have a less expensive hygrometer that I've "calibrated" with the table salt and water test. The cheaper model takes perhaps 15 minutes to adjust to the temperature and much longer (an hour?) to acclimate to the RH. The appeal of this upgrade was that it gives a supposedly accurate reading (plus or minus 3%) within a few seconds of turning it on. Unfortunately, the readings always conflict with the tool I've already calibrated; sometimes even the temperature -- an easier measurement than RH -- is off by two degrees. So, it appears this $80 tool out of the box is no better, or perhaps even worse, than others selling for half as much, and to improve on that, you'll have to pay much more to get a certified unit, or pay for the salt canisters and certify it yourself. ### ⭐ too much money for the quality *by on Reviewed in the United States 23 June 2019* it works fine but cheazy. totally not worth 70+ dollars. you can buy a same quality tool for far less. --- ## 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.com.sa/products/222129038-general-tools-digital-handheld-thermo-hygrometer-cmm880](https://www.desertcart.com.sa/products/222129038-general-tools-digital-handheld-thermo-hygrometer-cmm880) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-09-04*
